SET-UP INSTRUCTIONS (continued)
IMPORTANT: Set-up work to be performed by qualified servicemen only.
6. 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 wheels 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 plunger 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). Repeat until line is air free. Close bleed screw. Top off master cylinder as needed to prevent
reintroducing air into the lines.
Repeat with remaining wheel.
Contamination with dirt, water, petroleum products or other materials may result in brake failure or costly
repairs.
8) IMPORTANT: Make sure to properly attach the gravity box (or other equipment) to the running gear.
Bolt all four corners of the gravity box 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 two
corners to allow more box flexibility.
MOUNTING WHEELS
The adjacent diagram shows the proper way to mount wheels with
straight holes (22.5x13 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.
