Sustaining a chainsaw
Correct upkeep is crucial if a chainsaw is to be protected to make use of and can present safety towards in poor health health from extreme noise and vibration. Keep the noticed in accordance with the producer’s suggestions with all of the safety units in environment friendly working order and all guards in place. It would have to be often serviced by somebody who’s competent to take action.
Operators have to be educated within the right chain-sharpening strategies and chain and information bar upkeep to maintain the noticed in protected working situation. Operators have to report any injury or extreme put on from day by day checks on the next:
- on/off swap;
- chain brake;
- chain catcher;
- silencer;
- information bar, drive sprocket and chain hyperlinks;
- aspect plate, entrance and rear hand guards;
- anti-vibration mounts;
- beginning wire for proper stress.
PPE
Employers have duties regarding the provision and use of personal protecting tools (PPE) at work. PPE is tools that may shield the person towards health or safety dangers at work. It may possibly embody gadgets corresponding to safety helmets, gloves, eye safety, high-visibility clothing, safety footwear, safety harnesses and respiratory protecting tools.
PPE ought to solely be used as a final resort, ie when all different methods to remove or
scale back dangers have been thought-about. When deciding on PPE, ensure it is CE marked and it fits the person by way of
measurement, match and so on. If multiple merchandise of PPE is worn on the similar time, ensure they can be utilized collectively, eg sporting safety glasses could disturb the seal of a respirator, inflicting air leaks. Guarantee that customers of PPE are instructed and educated on its use and it’s maintained and accessible always. Protecting clothing complying with the suitable commonplace ought to present a constant degree of resistance to chainsaw cut-through. Different clothing worn with the PPE must be shut becoming and non-snagging. Notice: No protecting tools can guarantee 100% safety towards slicing by a hand-held chainsaw.
Related PPE requirements:
Safety helmet to EN 397. It is suggested that arborists working from a rope and harness use a mountaineering type helmet. Listening to safety to EN 352-1. Eye safety: Mesh visors to EN 1731 or safety glasses to EN 166. Higher body safety: Chainsaw jackets to BS EN 381-11. Chainsaw jackets can present further safety the place operators are at elevated threat (eg trainees, unavoidable use of a chainsaw above chest peak). Nevertheless, this must be weighed towards elevated warmth stress generated by bodily exertion (eg working from a rope and harness). Gloves: Using applicable gloves is beneficial below most circumstances. The kind of glove will rely on a threat evaluation of the duty and machine. Contemplate the necessity for cover from cuts from the chainsaw, thorny materials and chilly/moist circumstances. The place chainsaw gloves are required these have to be to EN 381-7.
Leg safety to EN 381-5. (All-round safety is beneficial for arborists working in timber and occasional customers, corresponding to these working in agriculture.) Chainsaw boots to BS EN ISO 20345:2004 and bearing a protect depicting a chainsaw to indicate compliance with EN 381-3. (For infrequent customers engaged on even floor the place there may be little threat of tripping or snagging on undergrowth or brash, protecting gaiters conforming to EN 381-9 could also be worn together with steel-toe-capped safety boots.)
Lone staff
Lone staff shouldn’t be put at extra threat than different workers. Take into consideration and take care of any health and safety dangers earlier than individuals work alone. Contemplate the next:
- whether or not there’s a have to assess areas of threat together with violence, handbook dealing with, the medical suitability of the person to work alone and any dangers arising from the character of the office itself;
- whether or not there are any explicit necessities for training and ranges of expertise wanted;
- what techniques is perhaps wanted to oversee and keep up a correspondence with lone staff the place a threat evaluation exhibits that is obligatory. Keep away from working alone with a chainsaw. The place this isn’t attainable, make preparations for elevating the alarm if one thing goes mistaken. These could embody:
- common contact with others utilizing both a radio or phone;
- somebody often visiting the worksite;
- carrying a whistle to boost the alarm;
- an computerized signalling machine which sends a sign at a preset time except prevented from doing so;
- checks to make sure operators return to base or home at an agreed time.
You’re accountable for ensuring your workers obtain quick consideration if taken in poor health or injured at work. Your preparations will rely on the actual circumstances in your office and that you must assess what your first-aid wants are. At the least, you will need to have:

- info for all workers giving particulars of first-aid preparations.
You may resolve that you just want a first-aider, ie somebody educated by an authorized organisation, and who holds a qualification in first support at work or emergency first support at work.There is no such thing as a authorized requirement for operators to carry an emergency first-aid at work certificates however we advocate they achieve this. Anybody working with chainsaws wants
to be educated in emergency first support, and specifically how you can control main bleeding and take care of crush accidents. In distant websites, individuals who have been injured may additionally be susceptible to hypothermia. Be sure that operators at all times carry a personal first support equipment (incorporating a big wound dressing) with them and have cheap entry to a extra complete equipment.
Working with chainsaws-Fuelling and lubrication
Be sure that petrol containers are in good situation, clearly labelled, and supplied with securely becoming caps. Use containers specifically designed for chainsaw fuelling and lubrication. Match an auto-filler spout to the outlet of a petroleum container to cut back the danger of spillage from over-filling. Operators have to:
- keep away from getting filth within the gas system (this will likely trigger the chainsaw to be unreliable);
- securely exchange all filler caps instantly after fuelling/oiling;
- wipe up any spilt petrol/oil;
- preserve gas containers properly away from fires and different sources of ignition, together with the noticed itself (at the least 4 m is beneficial) throughout beginning and use.
Don’t enable operators to make use of discarded engine oil as a sequence lubricant – it’s a very poor lubricant and will trigger most cancers whether it is in common contact with an operator’s pores and skin. Beginning the chainsaw and pre-use checks When getting ready to make use of a chainsaw, operators have to verify:
- all nuts, screws and so on are tight;
- the noticed chain is accurately tensioned;
- the throttle can’t be squeezed except the throttle lock-out is pressed;
- they’re sporting the right PPE.
When beginning the noticed, operators want to keep up a protected working distance from different individuals and make sure the noticed chain is evident of obstructions. When beginning a chainsaw with a chilly engine, operators have to:
- place the noticed on degree floor;
- safe the noticed firmly, eg put a foot on the rear-handle base plate and a hand on the entrance deal with;
- set the controls as beneficial by the producer;
- pull the starter wire firmly. As soon as the noticed has began, operators have to rev the throttle to heat up the engine and verify that:
- the noticed chain stops moving when the engine revs return to idle;
- the chain brake is efficient when utilized at most revs or in response to the producer’s specification;
- the engine continues to run when the noticed is turned via 90° in any course;
- the cease swap works accurately;
- lubrication to the information bar and chain is working correctly.
These checks have to be repeated at common intervals all through the day. When beginning a chainsaw with a sizzling engine, operators could use the identical methodology as above. Alternatively, they’ll grip the rear deal with firmly between the knees and the entrance deal with with their left hand, pulling the starter with their proper hand. As soon as the noticed is working, operators ought to apply the chain brake earlier than moving off with the noticed. Most trendy chainsaws will enable sizzling beginning with the chain brake utilized.
Kickback
Kickback is the sudden uncontrolled upward and backward motion of the chain and information bar in the direction of the operator. This may occur when the noticed chain on the nostril of the information bar hits an object. Kickback is accountable for a big proportion of chainsaw accidents, a lot of that are to the face and components of the higher body the place it’s tough to offer safety. A correctly maintained chain brake and use of low-kickback chains (safety chains) reduces the impact, however can not totally forestall it. Be sure that operators use the noticed in a means which avoids
kickback by:
- not permitting the nostril of the information bar to unintentionally come into contact with any obstruction, eg branches, logs, stumps;
- not over-reaching;
- holding the noticed under chest peak;
- holding the thumb of the left hand across the again of the entrance deal with;
- utilizing the suitable chain velocity for the fabric being reduce.
Utilizing the chainsaw
Regardless of the job, verify the worksite completely to establish any potential hazards. That is significantly vital when finishing up felling or demolition work. Wherever attainable, preserve a transparent working space on the location. For any work with a chainsaw guarantee:
- the dangers from the work have been assessed and managed;
- the operator is competent to do the job;
- the operator wears the suitable PPE;
- the operator both stops the engine or applies the chain brake when not slicing with the noticed.
Guide dealing with

- at all times preserve hundreds near the body;
- get assist in the event that they want it;
- give themselves correct relaxation breaks.
Assist instruments
Operators will discover it so much simpler to observe these guidelines when you put money into a number of easy bits of kit corresponding to pulp hooks, log tongs and excessive raise wedges. Used accurately they are going to assist operators to do the job with a minimal of effort and with a straight again. Appropriate body place Whether or not on the bottom or up a tree, it is important that forces on the again are utilized evenly. Earlier than lifting, operators ought to take up a place which supplies safe footing and would not drive them into an ungainly posture. Place the toes aside with one leg barely ahead to maintain balanced. If operators are levering over a tree, moving items of timber, or simply selecting up a chainsaw – the easiest way to do it’s with bent knees, straight again and with the load as near the body as attainable.
That means they’re lifting with their robust leg muscle mass, quite than their again. Operators mustn’t lever over a tree with one hand pushing on the tree and one on the lever. The again might be stretched and twisted, and many of the load might be taken by the decrease again muscle mass. It is rather vital that operators have a great grip when lifting and are free to regulate their place for one of the best raise. Among the best strategies is to make use of correctly sharpened pulp hooks or log tongs. This may also protect their gloves and so they will not must bend to date.

Resting the noticed on the thigh when crosscutting and debranching takes the load off the decrease again muscle mass.
Operators ought to preserve near the noticed – this may also scale back the danger of kick-back. They need to intention to work at a peak the place they’ll simply assist the noticed on the tree with out stooping.
Dealing with timber
Operators ought to reduce the timber into manageable items, getting somebody to assist them with the bigger sections. They will usually keep away from having to raise by rolling, pivoting or sliding the wooden. The extra thought put into felling and processing the timber, the better this might be. Assist instruments will assist operators do the job safely. In the event that they do have to hold timber, they need to ensure the bottom is freed from obstacles and tripping hazards.
Heavy hundreds
Even good lifting strategies have their limitations in the case of heavy hundreds. Wherever attainable operators ought to use tools which supplies their body a giant benefit. A portable winch is beneficial for making use of giant forces when felling giant or awkward timber. It would additionally make it simpler to show over a big tree stem. Equally excessive
raise wedges enable operators to use forces properly in extra of these from a breaking bar – their use will spare operators’ backs and provides them far more control. Felling cushions are additionally accessible which can be utilized as a substitute of wedges. Exhaust gasoline from the chainsaw is used to inflate the cushion and drive the tree over. For some jobs, let a machine take the pressure.
Appropriate handbook dealing with is a part of doing the job correctly. Recognised training programs can be found for chainsaw work and for another duties involving timber dealing with. These will educate operators how you can do the job safely and effectively with out placing their again in danger. Earlier than felling begins on the worksite mini chainsaw B0972QW5J4:
- contact the homeowners of any overhead energy traces inside a distance equal to twice the peak of any tree to be felled to debate whether or not the traces have to be lowered or made lifeless;
- don’t begin work till you’ve gotten reached settlement on the precautions to take;
- verify whether or not there are underground services corresponding to energy cables or gasoline pipes which might be broken when the tree strikes the bottom;
- if there are roads or public rights of means inside a distance equal to twice the peak of the tree to be felled, be certain that highway customers and members of the general public don’t enter the hazard zone. It’s possible you’ll want to rearrange warning notices, diversions or site visitors control.
