MAINTENANCE
CLEANING & STORAGE
1. Brush or blow dust and debris out of the air vents using compressed air or a vacuum. Keep the air
vents free of obstructions, sawdust, and wood chips. Do not spray, wash, or immerse the air vents in
water.
2. Wipe off the housing and the plastic components using a moist, soft cloth. Do not use strong
solvents or detergents on the plastic housing or plastic components. Certain household cleaners may
cause damage, and may cause a shock hazard.
3. Routinely clean out the dust and debris that gathers under the tension housing, the oil outlet, and
around the bar and the chain sprocket. Otherwise it can jam up the sprocket, the chain, and the
lubrication system.
4. If the pole saw is not used for an extended period of time, remove the chain oil from the tank.
Briefly place the chain and the guide bar in an oil bath and then wrap in oil paper to dry.
CHECKING THE AUTOMATIC CHAIN LUBRICATION
Regularly check the functionality of the automatic chain lubrication in order to prevent overheating
and the subsequent damage to the guide bar and saw chain associated with it. For this purpose, align
the guide bar tip against a smooth surface (board, cut-in of a tree) and allow the pole saw to run. If
an increasing amount of oil appears, the automatic chain lubrication functions properly.
