Checking wear on cutting equipment

SAFETY INSTRUCTIONS

C. Checking chain lubrication

• Check the chain

A. Saw chain

lubrication each time you

refuel.

Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.

D. Adjusting chain lubrication

Check the saw chain daily for:

•Visible cracks in rivets and links.

•Whether the chain is stiff.

•Whether rivets and links are badly worn.

Compare the existing chain with a new chain to decide how badly it is worn.

When the length of the cutting teeth has worn down

min 4 mm

(0,16")

•When cutting dry or hard species of wood it may be necessary to increase lubrication. To increase the oil flow, first undo screw (A) then turn the adjuster screw (B) anticlockwise. Re-tighten screw (A). Remember that this will increase the oil consumption and you should therefore check the level in the oil tank more frequently.

to only 4 mm the chain must be replaced.

B. Chain drive wheel

Check regularly the degree of wear on the drive wheel. Change if it is irregularly worn.

C.Vibration damping system

Procedure if the lubrication does not function:

•Check that the oil channel

in the bar is not obstructed. Clean if necessary.

Check also that the O- ring is in position and is undamaged.

•Check that the oil channel

in the gear housing is clean. Clean if necessary.

•Check that the bar tip sprocket turns freely. If

the chain lubrication system is still not working after carrying out the above measures you should contact your service agent.

Check regularly that the vibration damper i free from cracks.

Check regularly the degree of wear on the rubber elements. Change if worn.

D. Guide bar

Check regularly:

• Whether there are burrs on the edges of the bar. Remove these with a file if necessary.

• Whether the groove in the bar has become badly worn. Replace the bar if necessary.

•Whether the tip of the bar is uneven or badly worn. If a hollow forms on one

side of the bar tip this is due to a slack chain.

•To prolong the life of the bar you should turn it over daily.

!WARNING!

Using faulty cutting equipment may increase the risk of accidents.
