WARNING:
When starting a grinder for the first time, or after installing a replacement wire wheel, it is most important
that the operator stand aside for at least one minute of rotation at full speed. This is the correct practice
since a wire wheel can disintegrate if it received damage during shipping or handling.
Installation
When you receive your unit, there are several things you should do immediately.
1.
Observe the condition of the shipping container and report any damage immediately to the commercial carrier
that delivered the product.
2.
Verify that the part number you received is the same as the part number listed on your purchase order.
3.
Mount grinder-buffer on solid bench. The grinder-buffer must be securely bolted to a rigid mounting surface. If a
pedestal is used, first bolt pedestal securely to floor and then bolt grinder-buffer to pedestal.
4.
Check grinder-buffer nameplate to make certain the rating is correct for the power source, voltage and
frequency.
Wire Wheel Adjustments (see Figure 1)
1.
Disconnect AC Power Cord from 115VAC receptacle.
2.
Adjust spark arrestor for approximately 1/16" clearance between it and the wheel.
Maintain 1/8" or less clearance between spark arrestor and the wheel as wheel wears.
3.
Adjust angle of tool rest on support to desired position and tighten nut securely. Adjust tool rest support on
guard to attain approximately 1/16" clearance between tool rest and grinding wheel (or wire brush) and tighten
nut securely.
Maintain 1/8" or less clearance between tool rest and wheel (or brush) as wheel wears.
4.
Adjust eyeshield to position aligning center of eyeshield in line of sight to tool rest.
Belt Grinder Adjustments (see Figure 1)
If the correct belt is not installed on the belt grinder, perform the following:
1.
Disconnect AC Power Cord from 115VAC receptacle.
2.
Remove the belt. To remove belt simply push down on underside of belt to compress belt tensioning spring.
Catch automatically holds slide in retracted position.
Remove the belt from idler pulley and drive pulley.
3.
Install the correct belt. Be sure belt lap faces in correct direction and the arrows on the back side of belt face
the correct direction of rotation. See Figure 1.
4.
Apply tension to belt. When belt is installed, release catch by lifting it.
5.
Check Belt Tracking. Manually rotate the belt while watching the belt movement.
Manually rotate the belt. Belt should track centered on the drive and idler pulleys.
To adjust belt left, move tracking lever down. To adjust right, move lever up.
If tracking lever is set in full Up or full Down position, refer maintenance section.
Optional Table Installation
1.
Disconnect AC Power Cord from 115VAC receptacle.
2.
Assemble Table hardware as shown in Figure 2 and mount Table Support Bracket in the location identified in
Figure 1.
