Use and Care Manual
MAINTENANCE AND INSPECTION
OIL FEEDING: Prior to oil feeding, ALWAYS disconnect the
plug from the power receptacle. Since the oil chamber is built
into the tool, it can be used approximately 20 days at 3-4 hours
a day, without supplying lubricating oil.
Just before there is no oil visible in the oil gauge window when
holding the hammer upright use the provided wrench to remove
the oil gauge. Be careful not to lose the rubber backing attached
below the oil gauge. Fill the chamber with oil.
Check the oil level daily, conrming the oil level is full. After
feeding oil be sure to securely clamp the oil gauge.
INSPECTING THE TOOL: Using a dull or worn tool can cause
motor malfunctions and degraded efciency. Replace with a new tool
when wear is noted.
Inspecting the Mounting Screws: Regularly inspect all mounting
screws and ensure they are sufciently tightened. Should any of the
screws be loose. Re-tighten immediately before use.
Maintenance of the Motor: The motor unit Winding is essential to
the power tool. Ensure the Winding does not become damaged or wet
with oil or water.
Inspecting the Carbon Brushes: The motor employs carbon brushes which
are consumable parts. When they become worn, or near to wear limit, it can
result in motor malfunction when the “Auto-Stop” carbon brush is equipped,
the motor will stop automatically. At that time, replace both carbon brushes
with new ones. Always keep brushes clean and ensure they slide freely within
the brush holders. The carbon brush can be removed by removing the cap
cover. Cap rubber and brush cap in the order at the interior.
NOTE: Due to continuing program research and development, the specications herein are subject to
change without prior notice.
Lubrication: Your tool comes has been properly lubricated and ready for use. It is recommended that tools
with gears be re-greased with a gear lubricant at every brush change.
Bearings: Every second brush change, the bearings should be replaced by a qualied technician.
Bearings that become noisy, due to heavy load or very abrasive material cutting, should be replaced
immediately to avoid overheating or motor failure.
Cleaning: Disconnect the tool from power source prior to maintenance or cleaning of the power tool. The
tool may be cleaned most effectively with compressed dry 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 and solvents damage plastic parts. Some of these are gasoline, carbon tetrachloride,
chlorinated cleaning solvents, ammonia and household detergents that contain ammonia.
