SECTION 1 AUTOCLUTCH INSTALLATION
The Autoclutch Option allows you to engage the blade using a toggle switch on the con-
trol panel. This section will instruct you on how to install the option yourself. If your auto-
clutch option was factory-installed with a new sawmill, you can skip to the next section.
1.1 Manual Clutch Lever Removal
1. Raise the saw head so the clutch mounting hardware is located so it is comfortable for
you to work on. Move the saw head forward or back on the frame so you will be able to
easily access the clutch turnbuckle.
2. Turn the key switch to the OFF position and remove the key. Remove the battery box lid
and disconnect the cable from the negative battery terminal.
DANGER! Before performing any service to this equip-
ment, turn the key to the OFF position, remove the key, and
disconnect the cable from the negative terminal on the saw-
mill battery. Remove the blade from the saw head. Failure
to do so will result in serious injury or death.
3. If installing the autoclutch to an electric-powered sawmill, disconnect and lock out the
incoming power supply.
DANGER! On electric mills, hazardous voltage inside the
disconnect box, starter box, and at the electric motor can
cause shock, burns, or death. Disconnect and lock out
power! Follow all applicable electrical codes.
4. Remove the drive belt housing covers to access the clutch handle and turnbuckle linkage.
5. With the clutch handle disengaged (up), locate the clutch pivot plate where both the long
and short turnbuckles are connected.

1. If you are installing the autoclutch option to a sawmill equipped with a Kubota, Caterpillar,
Yanmar diesel engine or G35 (G38) Kohler gas engine, install the provided collar spacer
to the autoclutch turnbuckle. Loosen the jam nuts and turn the inner and outer links until
they seperate. Install the spacer collar to the inner link. Reassemble the inner and outer
links and tighten the jam nuts.
See Figure 1-2.

See Figure 1-4. Remove the three socket head bolts and lock washers from the back of
the autoclutch drive assembly. Place the rear guard (Rev. D Only) over the three slotted
holes located under the engine/motor mount plate. Use the three socket head bolts and
lock washers to install the autoclutch assembly to the saw head.
4. Use the 5/16-18 x 1" bolt, washer, cable clamp, and lock nut supplied in the bag assembly
to secure the top of the autoclutch bracket to the saw head.
5. Connect the autoclutch link arm and turnbuckle to the clutch pivot plate using the previ-
ously removed bolt and nut. The turnbuckles will be adjusted after the autoclutch is
installed and operational.

the switch. Install the toggle switch through the panel hole. Position the switch body so
the switch operates up and down. Secure the switch to the panel with the supplied nylon
washer and rubber boot.
