Chipper Electric Braking System
The primary activation of the braking system is through
the brake controller of the tow vehicle to the electrical
chipper/tow vehicle connection through the chipper
wiring harness and into the electrically operated brake
assemblies. A secondary system starts with the chipper
battery through the breakaway switch, chipper wiring
harness and into the electrically operated brake assem-
blies. This secondary system is only operational when
the breakaway switch is activated. This system should
never be activated except for testing or in an emergency
chipper/tow vehicle separation.
Brake Adjustment
Adjust brakes at the following intervals. Refer to the axle
owners manual.
• After the rst 200 miles of operation when the brake
shoes and drums have seated.
• At 3,000 mile intervals.
• As use and performance requires.
Hinge and Friction Points
Chipper operation and longevity can be improved by
keeping all hinges and friction points lubricated. Altec
Environmental Products, LLC recommends that lubri-
cation be performed weekly. Use SAE 30 weight oil on
hinges and a premium grade, high temperature lithium
based EP #2 grease on friction points.
Drum and Feed Roll Bearings
Lubricate daily with a premium quality NLGI #2 grade
multipurpose roller bearing grease. Some suggested
greases are: Mobile Mobilith AW 2, Shell Alvaina Grease
2, Texaco 1939 Premium RB, Amoco Rykon Premium
Grease #2 or an equivalent. Grease each bearing daily
with three or four pumps using a standard grease gun.
Feed Roller Pivot Points
Feed roller pivot points have a non-greaseable, oil impreg-
nated bushing. Lubrication of these points will inhibit the
designed method of lubrication and may cause excessive
wear of the bushings and shaft.
Notice
Always lubricate bearings and ll fuel and hydraulic
tanks at the end of each work day. This will displace
any moisture in the bearings and tanks. Also lubri-
cate thoroughly prior to any extended shutdown or
storage.
Due to extended use or extreme conditions, additional
maintenance intervals and/or component inspections
may be necessary.
