MAINTENANCE

CHAIN OILER

See Figure 17.

nUse Premium Bar and Chain Lubricant. It is designed for chains and chain oilers and is formulated to perform over a wide temperature range with no dilution required.

nRemove the cap and carefully pour approxi- mately 2 oz. of bar and chain lubricant into the bar lube reservoir.

nReplace the cap and tighten securely.

nCheck and refill the bar lube reservoir every time the pole saw is used.

NOTE:  Do not use dirty, used, or otherwise con- taminated lubricants. Damage may occur to the oil pump, bar, or chain.

CHAIN MAINTENANCE

See Figure 18.

For smooth and fast cutting, the chain needs to be maintained properly. The following conditions indicate that the chain requires sharpening: 

nWood chips are small and powdery

nChain must be forced through the wood during cutting

nChain cuts to one side

During maintenance of the chain, consider the following:

nImproper filing angle of the side plate can in- crease the risk of a severe kickback.

nDepth gauge (or raker clearance) setting de- termines the height the cutter enters the wood and the size of the wood chip that is removed. Too much clearance increases the potential for kickback. Too little clearance decreases the size of the wood chip thus decreasing the chain's cutting ability.

nIf cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or sand on the wood, have service dealer sharpen chain.
