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 tube may be clogged. Open the motor cover (Fig. 11) and check the oil tube (left

of the gear transmission). Unclog the oil tube to allow lubrication and prevent overheating.

STORAGE & TRANSPORT

1. Loosen the saw’s tension after the cutting session 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 when storing 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, drain 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.

MAINTENANCE

CARBON BRUSH REPLACEMENT

To maintain the efﬁciency of the motor, we recommend inspect-

ing 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. 9) and check the brushes, located left of the

stator and pressed against the motor commutator (Fig. 10 - 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. 11) 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

ordered at wenproducts.com. Only genuine WEN replacement

brushes designed speciﬁcally for your tool should be used.
