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

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

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

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 ofuse.

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.

A.Electric Powered Saws-To adjust belt tension, loosen the four (4) motor mounting bolts and remove the belt guard. Tighten the two (2) adjusting nuts 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 re- attach the belt guard.

B.Gasoline Powered Saws -To adjust belt tension, loosen the four (4) jackshaft mounting bolts and remove the belt guard. Screw the adjusting bolt back to increase the tension. Proper belt tension is 4-5 lbs. of force with approximately 1/8" of belt deflection measured at a point halfway between the pulleys.

It is very important that the jackshaft and blade arbor remain parallel

NOTEto each other. This can be accomplished by using the

adjusting bolt located on the engine mounting plate to help keep the jackshaft from cocking.

Tighten the (2) nuts on the engine tensioning bolts that are at the rear of the weldment. Proper belt tension is 4-5 lbs. of force with approximately 1/8" of belt deflection measured at a point halfway between the pulleys. Tighten the engine mounting bolts.

Pull on the recoil to make certain everything moves smoothly andfreely. Iftherecoilpullshard,thebeltsareprobablyadjusted a little too tight. Belt tensions should be readjusted before continuing. Attach the belt guards to the saw. Make certain that the guards do not come in contact with the belts or each other. There are slots in the guard mounting plates so adjustments can be made if necessary. Tighten all bolts on the guards and their mounts.

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". 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.Inspecttheconveyorcartperiodically. Replacethewoodinsert 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.
