Check slewing brake function
The boom at rest is held by a multiple disk brake system
(Figure 6), and stopping of the boom is accomplished
by hydraulic brake valves that are built into the mani-
fold shown in (Figure 6). When the boom is activated,
pressure that turns the boom releases the mechanical
brake. When you are finished moving the boom, the
mechanical brake must be reapplied slowly, or damage
could result to the brakes or the boom. Slow braking
is accomplished by limiting how fast the oil can come
out of the brake area. This is done with a throttle check
valve. The throttle is preset at the factory and should
not be readjusted unless you first consult the Service
Department at Schwing America.

Remember, if the reapplication of the brake is misadjust-
ed, damage to the boom and the brakes can occur!
Check auto grease reservoir - if equipped
Fill the auto grease reservoir using the provided grease
zerk, located on the front of the reservoir (Figure 7).
Attached a conventional grease press and fill to the
proper level.
The grease filling zerk can be removed and relocated
to the alternative filling port. This port may allow better
access (Figure 7). The port can also be used to mount
a lubricant return or filler coupling.
