DRILL/HAMMER DRILL SELECTION DIAL

The selector dial allows the tool to be set for various drilling/hammer drilling applications. Depress release button and turn selector dial right or left depending on the below applications.

!CAUTION Do not operate the selection dial until the tool

come to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.

Do not use demolition or chipping bits such as bull points, chisels, spades, gouges, etc.

Drill only action: For drilling in woods, metals, plastics or other non concrete materials.

Drill with hammer action: For drilling in concrete, asphalt, tile or other similar hard materials.

TOOL TIPS

Following a few simple tips will reduce wear on the tool and the chance of injury to the operator.

NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The “cost” to maintain sharp and undamaged accessories is more than offset by the “time saved” in operating the tool with sharp accessories.

All hammers require a short period of time to warm up. Depending on the room temperature, this time may vary from approximately 15 seconds (90˚F) to 2 minutes (32˚F). A new hammer requires a break-in period before full performance is realized. This period may require up to 5 hours of operation.

Carbide tipped bits: Used for drilling stone, concrete, cement, brick, cinder block and other unusually hard non-metals. The Rotary Hammer is designed for “SDS” Carbide Tipped Bits up to 3/4 inch diameter.

Recall these instructions for safe operation:

1.Some materials require slow drilling speeds; whereas, others require higher speed to produce the best results.

2.All work must be supported or secured before drilling and steady, even pressure applied in line with the drill bit.

3.As the drill bit cuts through the opposite side, reduce the pressure and continue running the drill as the bit is withdrawn.

Materials such as glass, porcelain, ceramics, tiles, plastics, etc., should be drilled at low speeds with specially designed drill bits and lubricants.

DRILLING WOOD OR PLASTIC

Do not drill into wood with ! CAUTION dust extraction system

mounted. Wood chips are typically too large and will clog the dust channel.

If backing block is not used, ease up on the pressure just before the bit breaks through the wood to avoid splintering. Complete the hole from the opposite side immediately after the point breaks through. If bit binds, reverse the drilling operation to help remove the bit from the work.

DRILLING METAL

!WARNING Do not drill into metal with the dust extraction system

mounted. Hot metal chips can self-ignite or ignite parts of the dust extraction system.

Make a center punch in the material for easier starting. Use enough pressure to keep the bit cutting. If the bit is allowed to merely spin in the hole, it will become dull within a short time. When drilling a larger hole, it is faster and easier on your power pack to first make a smaller hole and enlarge it to the required size. Lubricate the tip of the bit occasionally with CUTTING OIL for easier metal drilling. If bit binds, reverse the drilling to help remove the bit from the work.
