Service and storage
To ensure long and reliable service, carry out the following maintenance regularly. Servicing and cleaning work on the product and the removal of the guards
may only be carried out after the motor has been switched off and the plug disconnected from the power supply.
1) Regularly check for obvious defects such as loose, dislodged or damaged chain and guide bar, loose fixings and worn or damaged components.
2) Check that covers and guards are undamaged and correctly fitted. Carry out necessary maintenance or repairs before using the product.
3) If the cutting device should happen to fail despite the care taken in manufacturing and testing, repair should be carried out by an authorized specialist.
4) Do not clean the product while it is running.
5) Ensure that all the fastening elements (screws, nuts, etc.) are tight at all times so that you can safely work with the product.
6) Check the product frequently for signs of wear. Replace worn or damaged parts.
7) Store your product in a dry place. To ensure a long service life all screw parts should be cleaned and then oiled.
8) Clean the product with a brush or cloth. Do not use any solvents or water to remove dirt.
Spread the saw chain (2) out with the cutting edges of the chain pointing in the rotational direction and side the chain into the groove around the guide bar.
(Fig. B/Fig. R)
Align the guide bar (1) and saw chain (2) assembly with the drive sprocket (A) and bolt (B).
Lay the saw chain around the drive sprocket and when lower the guide bar to install it to the bolt. (Fig. S/Fig. T)
Replace the cover (6) and then slightly tighten the grey Knob (4) clockwise. (Fig. D)
Do not tighten the grey Knob (4) completely in a way that another grey Knob (3) around the grey knob (4) can be tightened clockwise for chain tensioning.
When the chain tension is appropriate, keep tightening the grey Knob (4) completely.
NOTE: The saw chain (2) has not yet been tensioned. Tension the chain as described under
“Saw chain tensioning”. After operating the product for approximately 1 hour, adjust the chain tension again.
Saw Chain Tensioning
Always check the saw chain tension before use, after first cuts and regularly during use approximately every five cuts. After initial operation, new chains can
lengthen considerably. This is normal during the break-in period and the interval between future adjustments will lengthen quickly.
WARNING! Unplug the product from the power source before adjusting the saw chain tension! The cutting edges of the saw chain are sharp. Always wear
protective gloves when handling the chain!
Always maintain proper chain tension! A loose chain increases the risk of kickback! A loose chain may jump out of the guide bar groove! This may injure the
operator and damage the chain! A loose chain will cause rapid wear to the chain, guide bar and sprocket!
Tensioning the chain too tightly will overload the motor and cause damage, and insufficient tension can cause chain derailing, whereas a correctly tightened
chain provides the best cutting characteristics and prolonged working life! The chain life mainly depends upon sufficient lubrication and correct tensioning!
Check the chain tension using one hand to lift the saw chain (2) against the weight of the product. The correct chain tension is achieved when the saw chain
can be lifted by approximately 2-4mm from the guide bar (1) in the centre (Fig. B/Fig. C).
Turn the knob (4) clockwise to tighten the cover (6) completely.
