COATS CDH-9551 Electric-Hydraulic Tire Changer - Manual (Page 23)


7) Move the tool carrier arm to the outside in its work position with the bead loosener disk facing the tire.
If the split-ring is not inserted sufficiently on the rim, move the spindle until the split-ring is by the disk. Bring the disk forward (with the spindle
turning) until you “observe” the O-ring seating.
8) Lubricate the O-ring and its seating.
9) Position the locking ring on the rim with the help of the disk as shown in Fig. Y.
Move the tool carrier arm to its non-working position and close the spindle arms completely. Support the tire so that it does not fall off
the spindle.
DANGER! POTENTIALLY HAZARDOUS OPERATION!
Do it manually only if you are certain you can keep the wheel balanced. For large and heavy tires an ad-
equate lifting device must be used.
Take the mobile control unit to work position B.
10) Move the ramp to free the tire from the spindle.
11) Remove the tire.
DANGER!!
Do not inflate the tire with the wheel mounted on the spindle. Tire inflation is potentially hazardous and should
only be done by removing the tire assembly from the spindle and placing it inside a safety cage.
14 ORDINARY MAINTENANCE
WARNING!
Each maintenance operation must be performed only after the disconnetion of the plug from electric
network.
To ensure that this tire changer works perfectly over the years, carry out the routine maintenance schedule described below:
1) Lubricate the following parts from time to time, after a thorough cleaning with naphtha:
- the various swivels on the spindle
- the tool bracket slide runner
- the carriage guide plate.
2) Grease the spindle bracket swivel. Add the grease through the grease nipple (See Fig. J) using ordinary lubricating grease.
3) Frequently check the oil level in the hydraulic power pack. Use the dipstick under the reservoir cap.
If necessary top up with Esso Nuto H46 or similar hydraulic oil (eg, Agip Oso 46, Shell Tellus Oil 46, Mobil DTE 25, Castrol Hyspin AWS 46,
Chevron RPM EP Hydraulic Oil 46, BP Energol HLP).
4) Frequently check the oil level in the gear unit which, when the tool carrier bracket is completely lowered at end travel, should not
show the sight glass on the gear casing as completely empty. If necessary top up with Esso Spartan EP 320 or similar oil (eg, Agip F1 REP
237, BP GRX P 320, Chevron Gear Compound 320, Mobil Gear 632, Shell Omala Oil 320, Castrol Alpha SP 320).
If the oil in the gear unit or the hydraulic power pack has to be changed, note that the gear unit casing and the power pack reservoir
have specific drain plugs.
WARNING!
Dispose of the used oil in approved waste oil contaner
