ASSEMBLY AND ADJUSTMENTS
15
WARNING: Do not turn on the tool until it is fully assembled according to the instructions.
Failure to follow the safety instructions may result in serious personal injury.
TENSIONING THE CHAIN
1. Check the chain tension by pulling the saw chain away from the guide bar. A properly tensioned chain
should have roughly 1/8 inch (3 mm) of distance between itself and the bar guide (Fig. 4).
2. If adjustments are needed, loosen the cover locking knob one full turn.
Instructions continue on the next page.
ASSEMBLY OF GUIDE BAR AND SAW CHAIN
1. Place the saw body on a firm and level surface.
2. Rotate the bar guide bar lock counterclockwise (Fig.
1 - 1) to remove the cover from the saw’s body.
3. While wearing protective gloves, wrap the saw chain
around the guide bar, making sure that the teeth are
aimed in the direction of rotation (Fig. 7, p. 16). The
chain should be properly set in the slot running along
the entire outside edge of the guide bar.
4. Place the saw chain around the sprocket (Fig. 2 - 1)
while lining up the slot in the guide bar with the bolt
(Fig. 2 - 2) at the base of the saw and the chain ten-
sioning pin (Fig. 2 - 3) in the guide bar’s pin hole. The
chain tensioning pin may need adjustment to properly
align with the hole in the guide bar. Use the chain ten-
sioning wheel (Fig. 2 - 4) to adjust its location until it
fits in the guide bar.
5. Turn the chain tensioning wheel to preliminarily
tighten the guide bar enough that it stays in place.
While holding the bar still, place the cover back onto
the saw. Make sure the tab on the left end of the cover
goes into the slot on the body of the saw (Fig. 3 - 1).
Lock the cover in place with the cover locking knob
by turning it clockwise until it engages. Adjust tension
(next section).

NOTE: The saw chain must be tensioned properly in order to ensure safe operation. The chain
tension is optimal if the saw chain can be lifted 1/8 inch (3 mm) from the center of the guide bar.
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 completed since it shortens when cooling down. In doing
so, you can elongate the chain’s life and prevent damage.
