Maintenance/Service

PREVENTATIVE MAINTENANCE CHECK LIST. Application: All Models.

The normal operation of the SURFACE GRINDER produces extreme dirt and dust, along with levels of random vibration. Before operating the SURFACE GRINDER, the following service list should be accomplished. This list is for reference only and is not intended to be all inclusive. Other subject areas can be added at the discretion of the owner(s) and/or operator(s):

1)Check all fasteners for proper torque values. If a fastener requires re-torquing, consult a torque chart for proper value. Properly discard and replace any worn fastener with a factory approved, replacement part.

2)Check the V-belts for wear. Adjust or replace as necessary. Check pulleys for wear and proper alignment. Many loose materials created as a result of operating processes can be extremely abrasive.

3)Keep the SURFACE GRINDER clean. Wash the unit after each use. Keep loose materials from accumulating around engine cooling fins. Determine that the interior sections of the frame are free of material build-ups. Such build-ups can restrict the operating process and present a potential safety hazard. Clean and remove any material build-up from the SURFACE GRINDER after each use.

4)Engine service life can be extended with proper air cleaner maintenance. Consult the material supplied by the engine manufacturer for specific information.

5)Check for proper oil level. Always use clean, high quality engine oil. Change oil as required. Consult the material supplied by the engine manufacturer for specific information

6)Remove material accumulations from the exterior surfaces of the electric motor. The electric motor is a totally enclosed, fan cooled (TEFC) design. Keep the fan fins clear of material accumulations to enhance airflow over the motor exterior for cooling purposes.

DANGER

DO NOT PERFORM PREVENTATIVE MAINTENANCE CHECKS WITH THE ENGINE OR ELECTRIC MOTOR RUNNING. STOP THE POWER SOURCE AND DISCONNECT THE SPARK PLUG OR EXTENSION CORD BEFORE PERFORMING ANY MAINTENANCE TO THE SURFACE GRINDER. IF GASOLINE ENGINE POWERED, RECONNECT THE SPARK PLUG BEFORE RESTARTING THE ENGINE. IF ELECTRIC MOTOR EQUIPPED, TURN THE ON/OFF SWITCH TO THE OFF POSITION BEFORE RECONNECTING THE EXTENSION CORD. IMPROPER PROCEDURES CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.

CHECKING V-BELT TENSION AND ALIGNMENT.

Application: All Models.

Proper V-belt tension and alignment are essential for smooth transmission of horsepower and extended service life. Improper tension and alignment will accelerate V-belt wear and contribute to decreased productivity. The V-belt is tensioned at the factory with the maximum recommended tension force. Check the belt tension at least two times during the first day of operation as there will normally be a rapid decrease in belt tension until it has been run in. Check the belt tension every eight hours of operation thereafter and maintain tension within the recommended range. The correct operating tension for a V-belt drive is the lowest tension at which it will not slip under peak load conditions.

Tools Required:

1 each, 16 inch minimum length straightedge.

1 each, 10 lbs minimum capacity, tension scale or belt tension tool.

1)If the SURFACE GRINDER is powered by an engine, disconnect the spark plug wire. If powered by an electric motor, disconnect the extension cord or SURFACE GRINDER from the power source.

2)Position the SURFACE GRINDER on a suitable work bench with the V-belts approximately at waist level.
