ASSEMBLY & ADJUSTMENTS
10
WARNING! To avoid injury from accidental startups, be sure that the tool is switched off and disconnected
from the power supply before inspecting the unit, making adjustments or changing accessories.
ASSEMBLY OF THE POLE EXTENSION
Open the installation lock lever (Fig. 1 - 1). Insert the pole extension into the saw head until it clicks in place.
NOTE: the handle will only fit with the notch on the extension pole facing upward. Flip down the installation lock
lever to lock the pole extension in place.

TENSIONING THE SAW CHAIN
The guide bar and saw chain have already been assembled onto your pole saw. Before operation, it is necessary
to check the chain tension. The chain tension is optimal if the saw chain can be lifted about 2mm (1/16”) from the
center of the edge of the guide bar (not from the tip). To adjust the chain tension:
1. Disconnect the saw from the power supply. Always wear pro-
tective gloves when handling the saw chain to prevent injuries.
2. Loosen the chain cover lock knob (inside knob) (Fig. 2 - 1) of
the chain cover by a few rotations.
3. Adjust the chain tension by rotating the tension adjustment
wheel (outer wheel) (Fig. 2 - 2). Clockwise rotation increases
the chain tension; counter-clockwise rotation reduces the chain
tension. The saw chain is correctly tensioned if the chain can be
lifted about 2mm (1/16”) from the center of the guide bar.
NOTE: The saw chain must be tensioned properly to ensure safe
operation. 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.
TIP: Loosen the saw’s tension after the cutting session has been completed. Since the chain shortens when it cools
down, by loosening the chain you can elongate the chain’s life and prevent damage.
SECURING THE EXTENSION CORD
To prevent the extension cord from disconnecting during operation, fold the female end of the extension cord in half
and slide it through the plastic extension cord wrangler found hanging from power cord.
Place the folded half of the cord around the wrangler’s hook and pull down to secure it in place. This should help
prevent the cords from becoming unplugged.
