If in doubt, DO NOT PLUG IN THE TOOL. Using a power source with voltage less than the nameplate rating is harmful to the motor. For all grounded tools with American type plug. GROUNDING INSTRUCTIONS: This tool should begrounded while in use to protect the operator from electric shock. The tool is equipped with a three-conductor cord and three-prong grounding- type plug to fit the proper grounding-type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. Never connect the green (or green and yellow) wire to a live terminal. Your unit is for use on 115volts and has a plug that looks like,Fig. "A". An adapter Fig. "B" and "C" is available for connecting Fig. "A" type plugs to two-prong recap tacles. The green-colored rigid ear, lug, etc., extending from the adapter must be connected to a permanent ground, such as a properly grounded outlet box. FIG. A FIG. 0 FIG. C Adapter Grounding Blade Cover of Grounded Outlet Box ADDITIONAL SAFETY RULES 1. 2. 3. 4. 5. 6. 7. 8. 9. IO. 11. Wear a hard hat (safety helmet) and an ear protector if necessary. Be sure the drill bit is secured in place before operation. Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation. In cold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up hammering operation is difficult. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations. Hold the tool firmly with both hands. Always use the side grip. Keep hands away from rotating parts. Do not leave the tool running. Operate the tool only when hand-held. Do not point the tool at any one in the area when operating. The drill bit could fly out and injure someone seriously. When drilling into walls, floors or wherever ”live” electrical wires may be encountered, DO NOT TOUCH ANY METAL PARTS OF THE TOOL! Hold the tool only by the plastic handle or the side grip to prevent electric shock if you drill into a “live” wire. Do not touch the drill bit or parts close to the drill bit immediately after oper- ation; they may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS. HOW TO USE Bit grease 0 Coat the drill bit shank head beforehand with a small amount (about 0.5 -1 g; 0.02 - 0.04 02.) of bit grease. This chuck lubrication assures smooth action and longer service life. Installing and removing the drill bit To install the drill bit, align protrusion (A) with the red dot, then align the key groove on the drill bit shank with the red dot and insert the drill bit. Now turn the chuck cover 90 degrees. I I Fig. 1 *To remove the drill bit, turn the chuck cover until protrusion (A) is aligned with the red dot. Then slip out the drill bit. Key-groove I II Fig. 2 Side grip 0The side grip can be swivelled a full 360 degrees. To set it at any desired angle, unscrew the grip counterclockwise and swivel to the desired position. Then tighten it securely. (Keep the grip base in the barrel groove before tighten- ing in place.) Fig. 3 Depth rod .The depth rod is used to drill holes of uniform depth. Loosen the thumb screw set the depth rod to desired position, then tighten the thumb screw. Fig. 4 Handling dust collector 0 Use the dust collector for safe, sanitary overhead operations. Install the drill bit, Dust collector then fix the dust collector on the end by turning and applying pressure. Then secure it by turning the metal retainer clockwise. CAUTION: Empty the dust collector of its contents after drilling every 2 or 3 holes. Fig. ! How to work switchover mechanism 0 For Rotation + Hammering: Press the push rod indCDodirection. For Rotation only: Push rod Press the Dush rod in &+direction. Lb- CAUTION: Press the push rod as far as it will go. Failure to do so can cause rapid wear of the switchover mechanism. Fig. 7 Speed control screw , Switch action Tool speed is increased by increasing pres- sure on the trigger. To start the tool, simply pull the trigger. Release the trigger to stop. Fig. t .A speed control screw is providedso that tool speed (RPM) can be changed at the fully- pulled trigger position. Turn the speed control screw clockwise (+) for higher speed and counterclockwise (-) for lower speed. CAUTION: Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Hammer drilling operation .Position the drill bit at the location for the hole, then pull the trigger. Do not force the tool. Light pressure gives best results. Keep the tool in posi- tion and prevent it from slipping away from the hole. When holes become clogged .Do not apply more pressure when the hole becomes clogged with chips or par- ticles. Instead, run the tool at idle, then remove from the hole. By ...
