COATS 7665 AX/EX Tire Changer - Manual (Page 16)

MAINTENANCE INSTRUCTIONS
Read and follow all the maintenance instructions
provided in this manual to keep the machine in good
operating condition. Refer to the other materials
received with the unit and to the service bulletins
from the manufacturer for additional instructions on
proper maintenance and service. Regular inspec-
tions and proper maintenance are essential to pre-
venting accidents and injuries.
Before making any
inspection, adjustment, or
repair, disconnect the
power source and block out all moving parts to
prevent injury.
Keep the machine and the
immediate work area
clean. Do not use com-
pressed air to remove dirt and debris from the
machine. Foreign material may be propelled into
the air and into operator or bystander causing
personal injury.
Wear protective clothing
and use eye protection
when making any adjust-
ments or repairs to the machine.
A. The vertical slide should be cleaned with a
vaporizing solvent and then lubricated with
chassis grease once a month.
B. Check the adjustment of the mount/demount
head once a month. See instructions this page.
C. Check the fluid level in the table top transmis-
sion once every 3 months. If fluid shows on dip-
stick, level is satisfactory. If no fluid shows, add
an SAE 80 gear lubricant until fluid shows on
dipstick.
D. The table top, clamps, mount/demount head,
and other working surfaces should be cleaned
with a vaporizing solvent every month.
E. The clamps should be inspected and metal
chips and dirt removed from the serrations with
a wire brush once a month.
F. Check the tire pressure gauge function daily,
and check the accuracy monthly. Use a pressur-
ized tire and a high quality stick-type pressure
gauge. If necessary, adjust the dial of the
machine gauge. If the gauge is defective,
replace it immediately (part number 107985).
Contact COATS at (615) 641-7533. Check func-
tion of the pressure limiter weekly. Always rein-
stall the lens after adjusting the gauge.
G. Make sure all fasteners are securely tightened.
H. Make certain that all guards and covers are in
place.
I. Check for worn, damaged or missing parts
including grips and protective covers. Replace
them before allowing the unit to be used.
J. On a daily basis, inspect the unit and check to
be certain that all systems are operating normal-
ly. Detailed inspection and testing procedures
are specified for various components at regular
intervals. Set up a chart and assign responsibili-
ty for these items.
Replace any damaged or
missing safety decals.
They are available from
COATS, (615) 641-7533.
IMPORTANT: These instructions will help you ser-
vice the unit. Instructions are for a person with some
mechanical ability and training. No attempt has been
made to describe all basic steps. For example, how
to loosen or tighten fasteners. Also basic procedures
such as cycling systems and checking operation of
the equipment are not fully described since they are
known to anyone who does mechanical and service
work. Do not attempt to perform work beyond your
ability or at which you have no experience. If you
need assistance, call an authorized service center or
contact COATS directly.
