f.
Periodically remove the funnel and look into the hole to check for rising air bubbles in the
hydraulic oil.
g. Once the tires begin to rotate, they can be manually rotated in lieu of manipulating the
clutch, alternating between the left and right sides, instead of the engine clutch while
continuing to add the hydraulic oil.
h. As air is worked out of the lines, the oil level in the reservoir will start to fall. Do not let
the reservoir fall below the hydraulic oil return (dashed line in the picture below), but do
not fill it higher than the solid line.
i.
Continue to rotate the wheels and watch for air bubbles. Once the hydraulic reservoir is
free of air bubbles, the wheels and pump no longer need to be manually rotated.
j.
Using a 3/32nd inch hex key, remove the screw and o-ring at the side of the reservoir as
indicated by the arrow below.
k. Fill the reservoir to the bottom of the screw hole as indicated by the line below. DO NOT
OVERFILL THE HYDRAULIC RESERVOIR. If the reservoir is filled above the height of the
screw hole, the QUADROVER will not function properly and serious harm or damage may
occur.
l.
Reinstall the screw and o-ring and tighten by hand until snug; do not over-tighten.
m. Replace the pressure relief valve.
n. With the QUADROVER still firmly mounted on its platform, follow the instructions in the
Honda Engine manual to start the engine. Run the engine for a few minutes, let it cool
off, then check the hydraulic oil level. If the level has dropped, remove the pressure-
relief valve and repeat steps j through m.
8. Install the roll-cage:
a. Attach the roll-cage to the two pegs (like the one shown) on the left side of the
QuadRover.
