Assembly & Adjustments - Wen 4019 Manual

WARNING: To avoid injury from accidental startups, be sure that the tool is switched off and discon-
nected from the power supply before inspecting the unit, making adjustments or changing accessories.
ASSEMBLY OF THE POLE EXTENSION (Fig. 1)
Lift open the installation lock lever (Fig. 1 -1) with your thumb and index finger. 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 (Fig. 2)
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 2 mm from the center of
the edge of the guide bar (not from the tip). To adjust the chain tensioning:
1. Disconnect the saw from the power supply. Always wear protective
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 raised approximately 2 mm 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 sawing operation 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 (Fig. 3)
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.
