5.3 Operating Speeds
Your power tool is equipped with a variable speed adjuster. The speed may be adjusted
during operation by rotating the dial.
Slow Speed
Certain materials require a relatively low speed because at high speed the friction of the
accessory generates heat and may cause damage to the material.
Slow speeds usually are best for polishing operations employing felt polishing
accessories, when working on delicate projects like woodcarving or fragile model parts.
All brushing applications require low speeds to avoid wire discharge from the holder.
High Speeds
Hardwoods, metals and glass require high-speed operation. Drilling should also be done
at high speeds.
Higher speeds are better for carving, cutting, routing, shaping, cutting a dado or
rabbets in wood.
Let Speed Do the Work!
Increasing the pressure on the power tool is not the answer when it is not performing as
you think it should. Perhaps you should be using a different accessory, and perhaps an
adjustment in speed would solve the problem. Leaning on the power tool does not help.
6. Cleaning and Maintenance
Service
No user serviceable parts inside. Preventive maintenance performed by
unauthorized personnel may result in misplacing of internal wires and
components, which could cause serious hazard. We recommend that all power tool
service be performed by qualified personnel. Disconnect the power tool from the power
source before servicing.
Motor
The motor in your power tool has been engineered for many hours of dependable
service. To maintain peak efficiency of the motor, we recommend it be examined by
qualified personnel every six months.
Cleaning
To avoid accidents, always disconnect the power tool and/or charger from the
power source before cleaning. The power tool may be cleaned most effectively with
compressed air. Always wear eye protection when cleaning tools with
compressed air.
Ventilation opening and switches 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.
Extension Cords
If an extension cord is necessary, a cord with adequate size conductors that is
capable of carrying the current necessary for your tool must be used. This will
prevent excessive voltage drop, loss of power or overheating.
