SUBJECT: Safety Bar Installation Kit

for 6-Inch Chippers With Smart Relay

KIT # 75579-00

MODELS: CH6670H (76624),

CH611DH (76628), CH6993H (76635)

WARNING

Before inspecting or servicing any part of this machine,
shut off power source, remove key, disconnect the
battery cables and make sure all moving parts have
come to a complete stop.

The safety bar gives the operator the ability to immediately
stop the feed roller in a potentially dangerous situation. By
pushing the safety bar, which is located directly under the feed
chute, the operator shuts down the feed roller and no more
material is fed into the chipper. The operator must push the
reset button to restart the feed roller and resume chipping.

EXTENSION TRAY INSTALLATION

1. Remove existing extension tray.

2. Install extension tray from kit, using existing hardware
except for the middle hole. For this hole, use the flange
nut, two washers, nylock nut, and 1-1/2" bolt as shown
in Fig. 1 to accommodate the kneebar switch shield.

3. Mount the cable mount clamp and tie with the 1/4" nut
and 1" bolt in the existing hole on the left side of the
chute (see Figure 2).

4. Secure the electrical harness from the extension tray with
the clamp mounted in step 3. Use the rest of the nylon ties
to secure the harness to the existing harnesses, leading
it up to the switch box cover.

operation, push in the reset button and hold to override
and reengage the feed roller.

Upon start-up, the red light will be on and the operator must
push the reset button before the feed roller will operate.
