MAINTENANCE (SAW)

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 - Shut-down the Saw for Maintenance

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

Electric Powered Saws

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.

Gasoline Powered Saws

Turn the engine switch to the OFF position, disconnect the spark plug wire and secure it away from the spark plug.

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

Basic Maintenance

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

2.Clean the machine frequently. Remove the belt guard and clean the pulleys. The belts and pulleys will wear rapidly if excessive dust builds up.

3.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.

4.After each day's use, clean the sludge from the bottom of the tray and run clean water through the water pump and water hoses. This extends pump and blade life.

5.Lubricate the blade adjustment rod after every eight

(8) hours of use.

6.Check the spindle bolt for tightness periodically.

7.Keep the drive belts tight. It is very important to replace worn belts as soon as possible.

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

9. The blade flanges must have a diameter of 4 in. Undersize flanges will reduce blade life and cause breakage. Therefore, they should be replace at once.

10.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.

11.Inspect the conveyor cart periodically. Replace the wood insert and wheels when necessary.

12.Lubricate spindle bearings after each day's operation. When dry cutting, grease bearings several times during the day's operation to protect them from the dust.

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

14.Grease pivot bearings periodically.

Bearing Lubrication Care

There are two (2) grease points (Figure 27) for the MP2 (Electric Motors) and four (4) grease points for the MP2 (Gasoline Engine). Use only Premium Lithium 12 based Grease, conforming to NLG1 Grade #1 consistency. Grease daily.
