PREVENTATIVE MAINTENANCE CHECK LIST.

The normal operation of the Crack Saw produces extreme dirt and dust, along with levels of random vibration. Before operating the Crack Saw, 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 retorquing, 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 Crack Saw 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-up. Such a build-up can restrict the operating process and present a potential safety hazard. Clean and remove any material build-up from the Crack Saw 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 air flow over the motor exterior for cooling purposes.

DANGER

DO NOT PERFORM PREVENTATIVE MAINTENANCE CHECKS WITH THE ENGINE RUNNING. DISCONNECT THE SPARK BEFORE PERFORMING ANY MAINTENANCE RECONNECT THE SPARK PLUG BEFORE 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 is 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)Position the Crack Saw on a suitable work bench with the V-belts approximately at waist level.

2)Disconnect the engine spark plug wire.

3)Remove the belt guard from the main frame. Clean the inside of the belt guard with an appropriate solvent. Check for signs of wear and damage. Secure in a proper storage area.

CAUTION

Observe all applicable safety precautions for the solvent.

4)Check the belt tension using the spring scale or belt tension tool midway between the engine/motor pulley and the arbor shaft pulley. Belt tension should measure approximately 0.22 inch at 3-1/4 to 4-3/8 lbs. measured force range. FIGURE 35. If tension is within specifications, proceed to Step 5. If tension is not within specifications, refer to INSTALLING A REPLACEMENT V-BELT for specific information.
