cylinder is located under the front hood. Use DOT 3 Motor Vehicle Brake fluid. Maintain fluid level within 1/4" of
master cylinder filler opening.
TIRE CARE
See
SECTION 1 INTRODUCTION,
VEHICLE SPECIFICATIONS for recommended tire pressure. Improper inflation
will shorten the life of your tires and will adversely affect performance.
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.
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.
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.
