Secure the Wheel on the Turntable
Before you can demount a Tire, you must secure the Wheel on the Turntable.
The Tire Changer supports two ways of securing the Wheel to the Turntable:
•
External clamping
. The Clamps are on the outside, pressing inwards.
•
Internal clamping
. The Clamps are on the inside, pressing outwards.
As a general rule, steel Wheels clamp internally and custom and mag Wheels clamp externally. Check
with your Supervisor if you are unclear about which method to use.
To secure a Wheel on the Turntable
:
1.
Make sure you are wearing OSHA-approved (publication 3151) personal protective equipment:
leather gloves, steel-toed work boots, back belts, hearing protection, and ANSI-approved eye
protection (safety glasses, face shield, or goggles).
2.
Identify the Narrow side of the Tire; this side goes up.
3.
Determine which clamping method you are going to use and move the Clamps to the starting
position for that clamping method:
–
If you are clamping
externally
, move the Clamps all the way
out
.
–
If you are clamping
internally
, move the Clamps all the way
in
.
4.
Put the Wheel onto the Turntable, either between the Clamps that are all the way out for external
clamping or over the Clamps that are all the way in for internal clamping.
5.
Secure the Wheel by pressing down and then releasing the Clamps Foot Pedal.
Tip
Clamping externally can be difficult on some Tires. If you are having problems getting the
Clamps to clamp externally, either press down on the Wheel from above or, if you are
using the R76ATR, use the Restraint Cone to push the Wheel down from above. Pushing
down from above moves the Rim away from the Tire a little, making it easier for the
Clamps to grab the Rim.
6.
Check to make sure the Wheel is securely clamped.
