Troubleshooting

Problem
The speed controller does not adjust for a change in
load, or shuts off before the knob (16) is turned all
the way down.
The speed controller does not maintain a consistent
speed, or the speed rapidly fluctuates.
Upon startup, the motor runs away for a few seconds
before the speed controller slows it down.

Solution
Remove the needle (13). and liberally lubricate the
needle and o-ring (33) with multi-purpose lithium
based grease.
Replace the needle (13), u-cup (11), and o-ring (33),
using Repair Kit 24J886.
Ensure that the compression nut (24) and flange
connector (23) are securely tightened to the motor
shaft. See Installation, page 3 .
