Genesis GHG 16 - GHG 50 Handling Grapple 45

TROUBLE-SHOOTING GUIDE

Rotation Speed Adjustment

For models GHG 16 - GHG 40 with the single motor option

The rotation speed can be adjusted clockwise and counterclockwise independently from each

other.

1. Remove both covers (s9) from the side of the swivel top (m27).

2.

When the covers are removed, two flow regulators (fr) will be visible.

3. These regulators are locked with a (3/32”) locking screw (c6). The screw must be loosened

before the flow regulators can be adjusted.

4. By turning the adjustment knobs, you can either slow down or accelerate the rotation

speed.

Be sure to tighten the locking screw when rotation spped adjustment is completed.
