CHECKING THE AUTOMATIC CHAIN LUBRICATION
Regularly check the functionality of the automatic chain lubrication. If the saw chain is dry when running with suf-
ficient oil in the oil tank, then the oil flow channel may be clogged. Open the motor cover (Fig. 11) and check the oil
channel located up and right of the gear transmission. Unclog the oil flow channel to allow lubrication and prevent
overheating.
STORAGE & TRANSPORT
1. Loosen the saw’s tension after the sawing operation is competed since the chain shortens when it cools down. In
doing so, you can elongate the chain’s life and prevent damage.
2. Always put the protective cover onto the bar and chain for transport or storage of the pole saw. Secure the tool
during transport to avoid damage or injuries.
3. Store the tool indoors in a dry, clean, and cool area. Keep it out of the reach of children. If the pole saw is not
used for an extended period of time, remove the chain oil from the oil tank. Briefly place the chain and the guide
bar in an oil bath and then wrap them in oil paper to dry.
CARBON BRUSH REPLACEMENT (Fig. 11 to 13)
To maintain the efficiency of the motor, we recommend inspecting the
two carbon brushes (see page 17, Part No. 4019-131) every 60 hours of
operation. Unscrew the 11 screws holding the motor cover on (Fig. 11)
and check the brushes, located left of the stator and pressed against the
motor commutator (Fig. 12 - 1).
The wear on the carbon brushes depends on how frequently and how
heavily the tool is used. Replace the brushes when the brush length (Fig.
13) gets down to 3/16 of an inch or when the tool sparks or stops working.
NOTE: Replacement carbon brushes (Part No. 4019-131) can be or-
dered at wenproducts.com. Only genuine WEN replacement brushes
designed specifically for your tool should be used.
