Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
document including all text under subheadings therein before set up or use of this product.
1. Prior to use check to make certain that the Axle
is straight, without any bends or damage.
2. Back off both Socket Set Screw (11) and slide off
one of the Center Cores (10) from Axle (12). Support
the wheel of the motorcycle in an upright position
and slide the Balancing Axle (12) through the wheel
hub and replace the Core. Center the wheel on
the Axle and slide both Cores securely against
the hub. Tighten the Socket Set Screws (11).
3. Lift the wheel and position the Axle over the Precision
Bearing (13). Gently spin the wheel. The heavier side
would roll to the bottom. With a chalk mark the tire at
the upper most location (across from the heavy side).
4. Lift the wheel assembly from the stand and place on
the floor. Attach a balancing weight (not supplied)
to the inner edge of the rim and reposition the
wheel assembly over the Precision Bearings (13).
NOTE: Use lightest possible weights.
With trial and error, you should be able to
establish approximate required weights.
5. Gently spin the tire. Repeat steps 3 and 4 placing
balancing weights on alternative sides of the tire rim.
6. Continue to counter balance the wheel until
it spins evenly and does not repeatedly
stop at any specific point of its rotation.
7. Once the wheel is balanced, remove the
assembly. Do not store or leave product in use.
Maintenance
1. Before each use, inspect the general condition
of the Balancing Stand. Check for loose
screws, misalignment or binding of moving
parts, cracked or broken parts, and any other
condition that may affect its safe operation.
2. Periodically lubricate contact points
and Rollers with grease.
Replacing Rollers
1. Precision Bearings (13) can be replaced by
removing Socket Set Screw (11) and pulling
Rollers off of the Balancing Stand.
2. Replace with new Precision Bearings (13) and
secure with Socket Set Screw (11). See Figure 2.
