SET-UP INSTRUCTIONS FOR RUNNING GEAR (Continued)
IMPORTANT: Set-up work to be performed by qualified servicemen only.
Adding Brake Fluid to the Master Cylinder.
IMPORTANT: Do NOT shake the brake fluid container. AVOID agitating the system when bleeding.
Do NOT “pump” the brake plunger. Instead, depress and release slowly.
Fill the master cylinder carefully, pouring the fluid down the side of the reservoir to minimize air
entrainment.
METHOD ONE (requires two people)
Close all bleed screws.
Start with the wheel furthest from the master cylinder. Slip a transparent bleed hose on the bleeder
stem and place the other end of the hose in a clean container which is partially filled with fluid at all
times.
The first person depresses the brake plunger SLOWLY (take 3-5 seconds). THEN the second
person opens the bleed screw. He then closes the bleed screw BEFORE the first person SLOWLY
releases the plunger (3-5 seconds). Continue until there is no evidence of air in the bleed hose.
Continue with remaining wheel working from the longest to the shortest distance from the master
cylinder. Top off master cylinder as needed to prevent reintroducing air into the lines.
REMEMBER:
1) Depress plunder slowly
2) Open bleed screw
3) Close bleed screw
4) Release plunger slowly
METHOD TWO (one person)
Attach bleed hose to rear wheel as in method one. Open bleed screw. SLOWLY depress plunger (3-
5 seconds) Let plunger return SLOWLY (3-5 seconds). Repeat until line is air free. Close bleed
screw. Top off master cylinder as needed to prevent reintroducing air into lines.
Repeat with remaining wheel.
Contamination with dirt, water, petroleum products or other materials may result in brake failure or
costly repairs.
IMPORTANT: Make sure to properly attach the gravity box (or other equipment) to the running gear.
Bolt all four corners of the gravity box runners to the running gear. (If the box is used in rough terrain
and it is not equipped with a rocking bolster, bolt a minimum of two corners and chain (or cable) the
remaining corners to allow more box flexibility).

MOUNTING WHEELS
Figure One shows the proper way to mount wheels with straight holes.
(22.5 x 13 wheels)
Use flange wheel nut (valve stem is on the outward side of the tire).
Wheels that are improperly installed on running gears, resulting in product
failure, will nullify warranty and shift the burden of liability to the owner/
operator of the equipment.
