Resumen del manual
A power source with voltage greater than that specified for the tool can result in SERIOUS INJURY to the user -as well as damage to the tool. 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: Thistool should be grounded while in use to protect the operator from electric shock. The tool is equipped with a threetonductor 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 recep- 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. Grounding Blade Cover of Grounded Outlet Box ADDITIONAL SAFETY RULES 1. Wear a hard hat (safety helmet) and an ear protector if necessary. 2. Be sure the bit is secured in place before operation. 3. 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. 4. Incold 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. 5. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations. 6. Hold the tool firmly with both hands. Always use the side grip. 7. Keep hands away from moving parts. 8. Do not leave the tool running. Operate the tool only when hand-held. 9. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously. IO. When chipping 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 chip into a "live" wire. 11. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin. SAVE THESE INSTRUCTIONS. I 0 Installingor removing'hull point or other bits (cold chisel, etc.) CAUTION : Always be sure that the tool is switched off and unplugged before installing or remov- ing the bit. Pull out and turn the tool retainer so that the boss on the tool retainer faces in the direction of the arrow. Insert the bit into the tool holder as far as it will go. Then turn the tool retainer 180 degrees to secure the bit. To remove the bit, follow the installation procedure in reverse. Fig. 1 Fig. : 0 Swivel handle The easy-grip handle swivels a full 360". This makes the demolition hammer ex- tremely handy for all kinds of operation. Fig. 3 Switch action To start the tool, simply pull the trigger. Release the trigger to stop. Trigger switch Fig. 1 CAUTION : Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the “OFF” position when released. Demolishing .Chipping -Scaling Choose the right accessories for your work. After mounting the suitable acces- sory and switching on the demolition hammer, let the mere weight of the tool itself apply pressure to the work surface. Fig. 5 MAINTENANCE CAUTION : ALWAYS be sure that the tool is switched off and unplugged before attempting to per- form inspection and maintenance. e Oiling Oiling should be performed every three hours (once a day before use). Hold the tool vertically and pull the lubrication knob three to five times. Oil in the tank should be replenished about every 20 days, presuming 3 -4 hours’ operation daily, or when oil is out of sight through the window after placing the tool ver- tically. Fig. 6 To replenish, remove oil gauge with a wrench. 0 Replacing carbon brushes Both carbon brushes should be replaced Insulating tip after about 150 hours of use. When the resin insulating tip inside the carbon >f-- brush is exposed to contact the com- mutator, it will automatically shut off the motor. If carbon brushes wear out too quickly, ask Makita Authorized or Factory Service Centers to determine the cause before replacing them. Use only Makita carbon brushes. Fig. 8 Use the screwdriver to remove the screw holding the holder cap plate as shown in the figure. Fig. 9 Use the screwdriver to remove the brush holder cap as shown in the figure. Take out the worn brush, insert the new one and secure the brush holder cap.
