Starting the Engine (continued)
Chain Oiler
OPERATION
WARNING!
The cutting attachment may rotate when the engine is started!
5.When the engine starts, slowly move the choke lever to the "OPEN" position. See Figure 26. (If the engine stops after the initial start, close the choke and restart.)
Open
Figure 26
WARNING!
Never start the engine from the operating position.
IMPORTANT!
If the engine fails to start after several attempts with the choke in the closed position, the engine may be flooded with fuel. If flooding is suspected, move the choke lever to the open position and repeatedly pull the recoil starter to remove excess fuel and start the engine. If the engine still fails to start, refer to the troubleshooting section of this manual.
When the Engine Starts...
■After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit.
■Advancing the throttle makes the cutting attachment turn faster; releasing the throttle permits the attachment to stop turning. If the cutting attachment continues to rotate when the engine returns to idle, carburetor idle speed should be adjusted (see the next page).
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. See Figure 20. 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 lubri- cated 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. See Figure 21.

CAUTION!
The oil flow adjusting screw must be pressed in slightly in order to turn. Failure to do so could damage the pump and screw.
3.With a screwdriver, push in on the oil flow rate adjusting screw and turn in the desired direction (there are three incremental settings):
