Adjusting the Chain
WARNING!
Never attempt to install, replace, or adjust the chain with the engine running.
WARNING!
The saw chain is very sharp. Wear gloves to protect your hands when handling.
CAUTION!
1.Place the pole pruner on a clean, flat sur- face. (For readjustment during operation, shut down the engine, then allow the guide bar and chain to cool before proceeding with the adjustment procedure).
2.Loosen the sprocket cover nut with a plug wrench.
4.Pull the chain by hand along the top of the guide bar several times from the engine to the bar’s tip. The chain should feel snug but still pull freely.
5.Tighten the sprocket cover nut securely while lifting the tip of the guide bar.
A loose chain can jump off the guide bar causing damage to the chain and associated equipment. Always make sure the chain is properly adjusted; check more often when you are breaking in a new chain.
IMPORTANT!
Proper chain adjustment is essential for maximum performance, long chain life, and operator safety. Always inspect chain tension before operating the pole pruner.

6.Inspect the chain for correct adjust- ment (more frequently with a new chain). The chain should feel snug but still pull freely.
Chain Oiler
WARNING!
Never fill the oil reservoir nor adjust the oiler with the engine running.
IMPORTANT!
The service life of the chain and guide bar is affected by the quality of the lubricant. Using superior lubricant such as Shindaiwa Bar and Chain Oil will help ensure a long service life, For cold weather operation, mix bar and chain oil with an equal part of kerosene.
Filling the Oil Reservoir
NOTE:
The oil reservoir has a capacity sufficient to provide about 40 minutes of cutting time (when set to deliver the minimum flow rate, or about as long as you’ll get from a tank of fuel).
1.Place the pole pruner on a clean, flat surface with the oil filler cap facing up. Wipe off any debris from the oil cap and from around the oil filler neck.
2.Remove the oil filler cap and fill the reservoir with bar and chain oil, then replace the cap.

3.Wipe up spilled oil from the unit before restarting the pole pruner.
Adjusting Oil Flow Rate
CAUTION!
An increase in bar oil flow rate will speed oil consumption, requiring more frequent checks on the oil reservoir. To ensure sufficient lubrication, it may be necessary to check the oil level more frequently than at fuel tank refills.
The guide bar and chain are lubricated automatically by a pump that operates whenever the chain rotates. The pump is set at the factory to deliver a minimum flow rate, but it can be adjusted in the field. A temporary increase in oil flow is often desirable when cutting materials such as hardwood or wood with a lot of pitch.
Adjust the pump as follows:
1.Stop the engine and make sure the stop switch is in the OFF position.
2.Place the unit on its side with the oil reservoir up.
