ASSEMBLY
BASIC OPERATION
1. To operate the bench grinder, always wear safety glasses and stand to the side of the grinder (as opposed to in
front) before turning the tool on.
2. Turn the ON/OFF switch to the ON position. Once the tool is up and running, allow it to reach full speed before
grinding. This will take about 15 seconds (Fig. 9).
3. Hold the work piece firmly against the tool rest. Hold very small pieces with pliers or other suitable clamps.
4. Choose the suitable grinding wheel for you operation. The 60 grit wheel is good for small material removal and
sharpening. The 120 grit wheel is good for extremely fine removal.
5. Feed the work piece smoothly and evenly into the grinding wheel. Move the workpiece back and forth at an even
pace to make for even grinding and prevent burning any one area of the surface.
NOTE: Sparks are normal during grinding operations. Protect yourself and the surrounding environment from
flying sparks.
6. Move the work piece slowly and avoid forcing the workpiece against the grinding wheel. If the wheel tends to
slow down from excessive force, you should occasionally release the pressure to let the wheel return to full speed.
NOTE: Excessive pressure may damage the tool, cause the motor to overheat, and prematurely wear down the
grinding wheel.
7. Grind only on the face of the grinding wheel; never on the side of it.
8. Regularly place the hot end of the workpiece into the coolant tray to cool it off.
9. Turn the ON/OFF switch to “O”. The wheels will take about 3 minutes and 20 seconds to come to a full stop.
Avoid contact with the bench grinder’s housing until it has stopped and cooled down completely. Unplug the tool
from the power source.
MOUNTING TO THE WORK SURFACE (FIG. 7)
The bench grinder should be firmly attached to a reliable work surface using mounting hardware (not included)
through the base of the grinder’s mounting holes.. This will prevent the bench grinder from vibration, walking or
tipping during operation.
NOTE: This bench grinder is compatible with the WEN 4288 Cast Iron Bench Grinder Pedestal Stand.
1. Prepare 1/4 in. bolts, flat washers, lock washers and hex nuts (not included). The bolt length should be 1-1/2 in.
longer than the thickness of the workbench.
2. Locate and mark the holes where the grinder is to be mounted onto the work surface. NOTE: If mounting to a
work bench, drill four 3/8 in. diameter holes through the workbench.
3. Place the bench grinder onto the workbench, aligning holes in base with holes in the workbench.
4. Insert four 1/4 in. diameter bolts and washers and attach with nuts securely.
