Basic Maintenance

MAINTENANCE

A good preventive maintenance program of regular inspection and care will increase life and improve the performance of the saw and cutting blades.

WARNING

Whenever cleaning, adjusting, or lubricating any part of the saw, MAKE CERTAIN to do the following:

•Place power ON/OFF switch to the OFF position.

•Disconnect power cord from AC source.

•NEVER attempt to check the V-belt with the engine running. Severe bodily injury can occur.

1.Tighten loose nuts or screws and replace any cracked or broken parts.

2.Clean the machine frequently. DO NOT use aggressive cleaners (i.e. containing solvents). DO NOT use high high-pressure water jets, aggressive detergents or solutions and liquids with a temperature exceeding 86°. Use a fluff-free cloth only. Use a cloth which may be lightly moistened only for removing dust and dirt. Hard packed dirt can be removed with a soft brush.

DO NOT let any water/cleaning liquid/vapor penetrate into the electric motor, connectors/plugs, switches, etc. Cover all apertures, holes in the housing, connectors or plugs, etc, or seal them with adhesive tape.

Use a soft, low-pressure water jet and a brush to rinse dirt and incrustations away. Be particularly careful when near hazardous parts of the machine (e.g. switch, motor). Clean the motor and switches only by wiping with a moist cloth.

3.Remove the belt guard and clean the pulleys.The belts and pulleys will wear rapidly if excessive dust builds up.

4.Clean the sludge that accumulates on the bottom of the water tray at least once a day and refill with clean water. It may be necessary to clean the tray out twice a day in heavy cutting. The sludge is abrasive and will shorten the life of the water pump and blades.

5.After each day's use, run clean water through the water pump and water hoses. This extends pump and blade life.

6.After cleaning, remove all covers and adhesive tape. All screws or nuts which may have been loosened must be retightened.

7.Check the spindle bolt for tightness periodically.

8.Keep the drive belt tight. It is very important to replace worn belts as soon as possible. To adjust belt tension, loosen the four (4) motor mounting bolts and remove the belt guard. Tighten the adjusting nut on the back of the motor plate to increase the tension. Proper belt tension is 4-5 lbs. of force with approximately 3/16" of belt deflection measured at a point midway between the pulleys.Tighten the motor mounting bolts and reattach the belt guard.

9.MAKE CERTAIN that the cutting head is aligned properly. Misalignment can adversely affect blade life.

10.The blade flanges must have a diameter of 4". Undersized flanges will reduce blade life and cause breakage. Therefore, they should be replaced at once.

11.Cutting blades must fit the arbor snugly. This is very important with diamond blades as pounding will occur and serious blade damage can result. If the arbor shoulder of the inner blade flange is grooved from blade slippage, the flange must be replaced.

12.Inspect the cutting table periodically. Replace worn parts.

13.DO NOT “rinse” the bearings of the drive elements to prevent them from running dry.The ball bearings of the machine are permanently lubricated.

14.Replace the spindle bearings as soon as they begin to make any strange noises. Worn bearings can destroy blades very quickly.

15.Grease pivot bearings periodically.
