• Remove the side plate (6) by turning the locking nut (5) in an anti-clockwise direction, remove it and set to the side (Fig A).
• Now take the chain bar (7) and with the logo side facing you rotate the metal disc anti-clockwise until it moves into the furthest
position to the right.
• Fit the chain onto the bar between the 2 plates so that the cutting teeth face in the right direction – note the symbol on the bar
which shows the correct orientation.
• Holding the chain taut, place the bar onto the body of the machine so that the threaded bar goes through the hole in the centre
of the disc, and the chain ts around the sprocket. (Fig. B)
• Ensure that the teeth on the chain t correctly around the sprocket. If not then rotate the sprocket a little and rotate the disc
clockwise to take up any slack.
• While supporting the weight of the bar, place the side plate back onto the machine ensuring the tab (Fig C 3) ts into the slot
and rotate the locking nut so that it is attached loosely. (Fig. C 1)
• Finally rotate the black collar around the locking nut (Fig. C 2) to bring the chain to the correct tension, then tighten the locking
nut.

Re-tensioning the saw chain
When working with the chain saw, the chain expands as a result of the warming. It then becomes slack and may slip o the guide
bar.
It is necessary in this situation to re-tension the chain. Once nished working it is important to release the tension before the
chain cools.
See the images below for correct tensioning of chain

General Maintenance

Insufficient chain lubrication
If after running the chain saw for about 20 minutes only a little lubricating oil has left the container, the cause may be blockage of
the oil duct in the saw and/or the oil hole in the guide bar. If so, they should be cleaned. To clean the oil duct the cover plate can be
removed, if necessary, after unscrewing its fastening screw.
Saw chains
Working with a blunt saw chain causes the chain, guide bar and drive sprocket to wear rapidly and may even lead to the chain
breaking and so it is important that the saw chain be e-sharpened by a competent workshop.
The relevant angles on the saw-chain cutters are:
• Side-plate ling angle:
• Top-plate cu ng angle:
• Top-plate angle:
• A 4mm diameter round le should be used for sharpening the chain.
