Power Feed Preliminary Test
This test will determine if the problem is a mechanical or electrical.
1.
Remove the drive belt from the power feed drive pulley.
2.
Turn the key switch to the ACC position. Put the carriage forward/reverse switch into the forward position and
turn the feed rate dial through all speeds. If the power feed motor runs properly at all speeds, the problem is a
mechanical one instead of an electrical one.

Power Feed Mechanical Test
1.
Remove the weight from the track rollers. They should turn smoothly and easily with very little play.
2.
Make sure the middle track cover is not bent or touching the top rail.
3.
Make sure the middle track oiler is free of sawdust buildup.
4.
Make sure the power feed chain is not stiff from rust. Also make sure the chain is not too tight.
5.
Check the power feed shaft. Visually inspect the bearings. The shaft should move neither in or out nor side to
side.
6.
Make sure the power feed chain cam bearing is not touching the main frame tube.
7.
Make sure there is no sap or rust on the rails.
8.
Make sure the block on the lower track roller assembly is not rubbing the lower rail. Also make sure the track
rollers are not too tight.
9.
Make sure the power feed belt is properly tightened.

Fuse Terminal Extension Stud
A fuse terminal extension stud is provided in the fuse box. The extension may be used to temporarily connect
a battery charger or jumper cables to raise the saw head from the towing position so the battery box lid can be
removed.
CAUTION!
The fuse stud extension is designed to provide enough power to
raise the saw head only. Do not attempt to start the engine or operate any
other electrical function until direct battery charging can be performed. Do not
attempt to move the saw head by attaching jumper cables from a secondary
power source to the up/down motor terminals. Damage to the electrical sys-
tem will result.
