Maintenance
– Never modify the chainsaw in anyway.
– Always maintain the chainsaw in good working order regularly serviced by an authorised
service agent.
– Ensure the handles remain clean and free from oil, fuel & moisture.
– Only use replacement parts supplied by the manufacturer.
– Ensure the chain does not rotate while the saw is at idle.
– All safety devices must remain fitted, functioning and where possible serviced.
Especially the chain brake.
– Only use fresh, clean and good quality fuel/oil mix in the chainsaw.
– Regularly inspect the chain lubricant level, regularly topping up. When the chainsaw is
running at high speed the chain oil will dispel quicker and require checking/adjusting
more frequently.
– Never operate the chainsaw without chain oil.
– Never operate the chainsaw with a maladjusted or blunt chain as this is highly dangerous.
– When the chainsaw has warmed up, stop the chain & engine before checking/adjusting
the tension.
– Never refuel in close proximity to naked flames, sparks or other sources of ignition, e.g.
cigarettes.
– Allow the engine to cool before refuelling. Avoid spillage while refuelling.
– Wipe up and correctly dispose of any fuel spillage immediately with a suitable medium.
– Ensure the correct ratio of fuel and oil are used.
– Do not set down a hot chainsaw on or near easily combustible materials. e.g. dry leaves
and grass.
– Move away from the refuelling area before restarting the chainsaw.
– Store fuel for short periods only and avoid mixing more than is required. Store in a
container specifically designed for petrochemical applications away from heat and direct
sun light.
– Prior to use check for chain oil distribution on a piece of paper or cut timber. Observe
spatter before continuing.
– After each use clean the chainsaw thoroughly.
– Regularly check external nuts and fixings to ensure vibration caused by normal use has
not begun to loosen them.
– Periodically remove all shavings and sawdust from the visible parts of the chain brake
mechanisms.
Storage
– Thoroughly clean/service the chainsaw and refit the bar guard. Remove the spark plug
ignition lead from the back of the spark plug and position the lead to avoid accidental
reconnection.
– Locate the machine out the reach of children, in a dry locked unit.
– Remove all residual fuel from the fuel tank before storing.

9.13 CHAIN LUBRICATION - FIG. 28
– Prior to use check for chain oil distribution on a
piece of paper or cut timber. Observe spatter before
continuing.
– If the chain is not sufficiently lubricated, check the oil
tank level and/or increase the oil flow by rotating the
setting screw anti-clockwise. If problem
persists, stop engine and when cooled clean
sawdust from behind clutch cover and clean bar
groove.
9.14 SHARPENING - FIG. 29
– Sawdust instead of chips is an indication that the saw
chain needs sharpening, or replacing.
– Before sharpening, the chain must be made taught by
means of the chain tensioner.
– After sharpening, slacken and adjust the chain as per
the mounting instructions.
– During sharpening, lock the chain using the brake.
– Use a round file specific for the chain fitted. Observe
the sharpening angle (Fig.29 parts 2,3,5,7,8).
– Sharpen by filing from the inside outwards (Fig.29
part 9) all the teeth on one side and then all the teeth
on the other.
– Position the file to project 20% of its diameter above
the cutter (Fig.29 part 6).
– Make sure every cutter is filed to the same length and
angle, and that all depth gauge links are the same
height (Fig.29 part 1).
– Inconsistent angles can result in a poor cut or
endanger the user. Seek advice from a professional if
unsure.
