POST OPERATION CARE & STORAGE
Disconnect the hydraulic hoses from the tool.
First the INPUT (Supply), then the Output (Return) hose.
Place dust plugs or caps on hose ends, couplers and/or tool ports as needed.
Remove the disc after use.
NOTE:
Never transport or store the tool with the cut-off wheel mounted on the saw.
TOOL CARE
Clean tool to remove dirt, grease or debris. Dry with compressed air or clean dry cloth.
Replace any damaged or missing safety labels and tags before storing.
Store the tool in a clean dry place.
DISC/WHEEL CARE
All abrasive discs/wheels are breakable.
Care should be taken to prevent damage during handling and storage.
Clean and inspect the wheel before storing.
Clean wheel to remove dirt, grease & debris.
Dry thoroughly.
Store wheels on a flat rigid surface of steel or comparable material.
Do not subject to high humidity, water or liquids.
Avoid excessive heat, freezing, or temperatures low enough to cause condensation if
temperature is increased.
INSTALLING & REMOVING GRINDING WHEEL
Inspect for chips, cracks, wear, or damage. Replace the wheel if it is worn or damaged.
1. Remove and set aside the jam nut from the output shaft.
2. Position the grinding wheel over the shaft.
3. Screw the jam nut down onto the spindle shaft. Tighten the nut securely by using two
open-end wrenches, one wrench on the flats of the spindle shaft, the other wrench on
the jam nut. NEVER over-tighten by impacting either wrench with a hammer or mallet.
4. Remove the grinding wheel by loosening the jam nut. (Reverse of Step 3)
PERIODIC INSPECTION & MAINTENANCE -
For maximum performance, reliability and
SAFETY of the tool, periodically check the following components.
DRIVE-SHAFT SPEED CHECK
The maximum rated speed of the Hydraulic Grinder is 2,700 rpm.
The rated speed of the disc must be equal to, or greater than that of the tool to ensure the
integrity of the wheel at maximum tool speed.
Use the hydraulic power supply normally used with the cut-off saw when conducting this test.
Excessive speed may be caused by increasded fl ow. Refer to SPECIFICATIONS on page 5.
Check the speed of the motor output shaft. (Every 100 hours of operation is recommended)
The test should be performed only by a trained, experienced technician.
Maintain a record of the checks.
