5.4 BRAKE FLUID MAINTENANCE
Check the brake fluid in the master cylinder periodically (under normal conditions, every 3 months). Use
DOT 3 Motor Vehicle Brake fluid. Maintain fluid level within 1/4" of master cylinder filler opening.
5.5 TIRE CARE
See Sect 1.4 for recommended tire pressure
. I
mproper inflation will shorten the life of your tires and will
adversely affect performance. Do not exceed maximum stated on tire sidewall.
NOTICE:
Replacement tires must be the same size as original equipment. Increased tire load
ratings are permissible but tire rating does not increase the rated load carrying capacity of the
vehicle.
5.6 WHEEL & TIRE REMOVAL/INSTALLATION
Place blocks ahead of and behind the wheels that will remain on ground. Slightly loosen lug nuts. Place a
jack under the side of the vehicle in contact with the frame. Raise vehicle and remove lug nuts and
wheels. To install, tighten the lug nuts evenly in a star pattern until the nuts are all seated and torque to.
65 ft. lbs. (88.1 N.m). Recheck lug nut torque with the vehicle on the ground
NOTICE:
The wheel may be bent if not torqued in a crossing pattern. This will cause the wheel
to wobble
5.7 CLEANING
Wash underside to remove all dirt and debris. Do not direct high pressure water at the controller, speed
switches, or tops of the batteries.
Wash body and seat with a mild detergent. Do not use abrasives (bodies are painted). Frequent washings
with mild soap will preserve the finish of your vehicle. For stubborn and imbedded dirt, a soft bristle brush
may be used. Tar, asphalt, creosote and the like should be removed immediately to prevent staining of
paint.
NOTICE:
Do not use harsh detergents, abrasives or cleaning solvents that contain ammonia,
aromatic solvents or alkaline material to clean cab.
5.8 LUBRICATION
Every 6 months apply light oil to the rear body hinges.
Semi-annually grease the vehicle chassis. There are seven fittings: three on each side of the front
suspension and one on the brake pedal pivot. Use a high quality grease. Remove the weight from the
front suspension before lubricating to ensure proper grease distribution.
The differential should be checked periodically for signs of leakage. Contact your Columbia Dealer for
fluid replacement.
