ASSEMBLY AND ADJUSTMENTS
WARNING: Always be sure that the tool is switched off and unplugged before adjusting, adding accesso-
ries, or checking a function on the tool.
ASSEMBLY OF GUIDE BAR AND SAW CHAIN
1. Loosen the cover release knob (Fig. A - 1) to release the chain
sprocket cover. Remove the chain sprocket cover.
2. Place the chain in the groove of the outside edge of the guide
bar as shown. NOTE: make sure the chain’s direction of rotation
is correct. The blades on each cutting link on the upper side of
the cutting bar must be facing towards the tip of the chainsaw.
3. Insert the guide bar and chain into the mount on the chainsaw
(Fig. B). In the process, guide the chain around the pinion and
hang the guide bar in the chain tensioning bolts.
4. Adjust the chain tension (see the following section - TEN-
SIONING THE CHAIN). Mount and hand-tighten the chain
sprocket cover with the retaining nut
TENSIONING THE CHAIN
1. Loosen the retaining nut of the chain sprocket cover by a few rotations.
2. Adjust the chain tension by rotating the Tension Adjustment Knob (the outermost knob on the cover release
knob). Clockwise rotation increases the chain tension; counter-clockwise rotation reduces the chain tension. The
saw chain is correctly tensioned if it can be raised approximately 2 mm from the center of the guide bar.
NOTE: The saw chain must be tensioned properly in order to ensure safe operation. The chain tension is opti-
mal if the saw chain can be lifted 2 mm from the center of the edge of the guide bar (not the tip). Since the saw
chain heats up during operation, its length can therefore fluctuate. Check the chain tension every 10 minutes of
operation and adjust as necessary, particularly for new saw chains. Slacken the saw chain after the work is com-
peted since it shortens when cooling down. In doing so, you can elongate the chain’s life and prevent damage.
SAW CHAIN LUBRICATION
Always unplug the unit from its power source before inspection and adjustment work. Wear protective gloves dur-
ing maintenance to prevent injury.
Never operate the chainsaw without saw chain oil. The use of the chainsaw without enough saw chain oil will dam-
age the unit.
Only use special saw chain oil. Other oils will run the risk of damaging the unit and voiding the warranty.
Take note of temperature conditions. Using the saw at various temperatures requires the use of differing oils. To
ensure a sufficient layer of lubricant at lower temperatures, use liquid oil (low viscosity).
