CHECKING AND SETTING THE AUTOMATIC CHAIN OILER
0035
The automatic chain oiler provides a constant supply of oil to lubricate the bar and chain whenever the saw is operating. An
adjustment screw controls the amount of oil supplied (Figure 3).
1.
Run the saw at full rpm (WP 0004).
2.
If the tip of the saw gives off a fine spray of oil, the automatic oiler is working properly. If the saw does not give off a
spray of oil, adjust the oiler.
NOTE
For better results, hold saw so that the tip of the saw blade is pointing toward a clean sheet of paper
or cardboard and run the saw at full rpm. If the automatic oiler is working properly, the paper or
cardboard should soon show small droplets of oil.
3.
Stop the hydraulic power source (WP 0004).
4.
Twist the adjustment screw 1/2 turn as follows:
clockwise to decrease the oiler output.
counterclockwise to increase the oiler output.
5.
Start the hydraulic power source (WP 0004).
6.
Repeat until the oiler output is adjusted correctly (Figure 3).
