Maintenance

Service

Preventive maintenance ! WARNING performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service be performed by a Bosch Factory Service Center or

Authorized Bosch Service Station.

TOOL LUBRICATION

Your Bosch tool has been properly lubricated and is ready to use. However it is recommended that the gears be relubricated only with Bosch lubricant: WD7LUB or Skil 80111.

Always check the oil level before using the saw. To check and add oil: Remove plug from power source and

place the saw’s foot on a horizontal surface. Remove oil plug using the same wrench used to remove the saw blade. The oil level should never be below bottom threads in the housing. When adding oil, fill until oil starts to run out of oil hole at arrow on housing and replace oil plug.

NOTE: If oil is extra dirty or thick, replace the plug and run the saw for one minute to warm up the oil. Then remove oil plug and turn saw upside down, to remove all oil. Fill housing with kerosene. Replace plug and run for one minute to flush out the gear housing. Drain out the kerosene and add fresh Bosch lubricant. With a new saw, change the oil after the first ten hours of use.

CARBON BRUSHES

The brushes and commutator in your tool have been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend every two to six months the brushes be examined. The brushes should be free from dust and dirt. Brushes should be replaced when they have worn down to 3/16" in length. The brushes should slide freely in and out of the holders without sticking.

To check brushes: Disconnect plug from power source. Unscrew the brush caps on the

motor housing and lift out the brushes; note which way they face, so that the brushes can be returned to their original position. Clean the brush holder openings with compressed air or a clean cloth and replace the brushes and caps.

Only genuine Bosch replacement brushes specially designed for your tool should be used.

BEARINGS

After about 300-400 hours of operation, or at every second brush change, the bearings should be replaced at Bosch Factory Service Center or Authorized Bosch Service Station. Bearings which become noisy (due to heavy load or very abrasive material cutting) should be replaced at once to avoid overheating or motor failure.

Cleaning

!To avoid accidents always WARNING disconnect the tool from

the power supply before cleaning or performing any maintenance. The tool may be cleaned most effectively with compressed dry air. Always wear safety goggles when cleaning tools with compressed air.

Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through openings.

!Certain cleaning agents CAUTION and solvents damage

plastic parts. Some of these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.

CARE OF BLADES

Blades become dull even from cutting regular lumber. If you find yourself forcing the saw forward to cut instead of just guiding it through the cut, chances are the blade is dull or coated with wood pitch.

When cleaning gum and wood pitch from blade, unplug the saw and remove the blade. Remember, blades are designed to cut, so handle carefully. Wipe the blade with kerosene or similar solvent to remove the gum and pitch. Unless you are experienced in sharpening blades, we recommend you do not try.
