Duckhead (Mount/Demount Tool)
Adjustment
To Adjust Tool Head Lift
Shoulder screw (ref.1) sets the tool head lift for
metal duckhead mount/demount tools – no adjustment
required. Place shim 85606345 on screw if using a
plastic duckhead mount/demount tool.
To Adjust Lock Tightness
With lock handle unlocked, loosen jam nut (ref. 3) and
adjust pin (ref. 4) until a slight firmness is obtained, then
tighten jam nut and check. Also recheck tool head lift at
this time.
Robotic Arm Maintenance
1.
Grease the Robo Arm™ to maintain smooth rota-
tion. Grease fittings have been provided at the pivot
joints.
2.
Check bolt torque periodically at pivot joints. Proper
torque is 240 ft. lbs.
Oil Injector Maintenance (if equipped)
The oil injector requires servicing at least annually.
The oil level in the oil reservoir tank should be checked
regularly.
Add oil to oil reservoir tank when fluid level is a quarter
full or below. Remove cap from the oil reservoir tank
and add Chevron Regal
®
R & O 32 oil to full line (air tool
oil is an acceptable substitute). Replace cap and clean
up any spilled oil.
Important: An air lock will form if the hose between
the reservoir and injector is ever empty of oil. In this
case, after filling the reservoir tank, the line must be
bled of air at the injector connection as follows:
1.
Disconnect all power sources, both air and electric-
ity inputs. Allow any stored air in the reservoir to escape
by depressing the inflate pedal.
2.
Remove the side panel and locate the oil injector.
3.
Prime the oil injector.
a. Oil Injector With Bleeder Screw
Loosen bleeder screw until oil drips from screw and
all air is relieved from the oil line hose. Retighten
the bleeder screw.
b. Oil Injector Without Bleeder Screw
Remove the oil line hose from the injector barb fit-
ting. Allow air to escape from the hose by lowering
the hose end below level of reservoir until oil is
present. Drip oil into hose barb fitting on injector
until barb fitting is full. Reinstall oil line hose onto
oil injector barb fitting.
4.
Reconnect air/electric sources and cycle the clamp
control pedal a few times checking for oil and air leaks.
5.
Test the machine for full function before returning
the machine to operation.
6.
Monitor oil consumption to ensure oil is being used
in system.
