5. Hold the tool firmly with both hands. 6. Keep hands away from rotating parts. 7. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced blade. 8. Make sure the blade is not contacting the workpiece before the switch is turned on. 9. Wait until the blade attains full speed before cutting. IO. Keep at least 200 mm (8”)away from the tool at all times. 11. Always switch off and wait for the blades to come to a complete stop be- fore any adjusting. 12.Never stick your finger into the chip chute. Chute may jam when cutting damp wood. Clean out chips with a stick. 13.Do not leave the tool running. Operate the tool only when hand-held. 14.When leaving the planer, switch off and set it with the front base up on a wooden block, so that the blades do not contact anything. 15.Always change both blades or covers on the drum, otherwise the resulting imbalance will cause vibration and shorten tool life. SAVE THESE INSTRUCTIONS. Removing or installing planer blades CAUTION : Always be sure that the tool is switched off and unplugged before removing or installing the blade. The blade is secured with four bolts. Re- move the inner two bolts entirely with the socket wrench and loosen the outer two bolts two turns each. Press down on the pin in the middle of the drum with one end of the socket wrench handle. The blade can be pushed and jiggled out so as to be removed. (If the blade becomes so short that it cannot be grasped, you must remove the four bolts and the drum cover. Then push the blade out with one end of the socket wrench handle.) To install the blades, first clean out all chips or foreign matter adhering to the drum or blades. Use blades of the same dimensions and weight, or drum oscilla- tionhibration will result, causing poor planing action and, eventually, tool break- down. Insert the blade, holding both ends, so that it protrudes from between the blade holder and the drum. Then secure the four bolts only finger-tight. Fig. 1 Fig. 2 Fig. 3 Stopper pin Align the blade edge with the mark and make the drum stationary by means of the stopper pin. Place the leveller over the rear base and blade, and press the leveller down slightly. Release the stopper pin. When released When secured ~ Fig. 4 Turn the drum in the direction of the arrow (Fig. 6) to check the blade protru- I -sion, holding the leveller flush against the Leveller blade and rear base. The blade edge should just contact the underside of the leveller. When the blade edge does not protrude far enough from the base, press down on the pin in the middle of the drum with the socket wrench handle, and adjust the blades again as mentioned above. After adjusting both blades, tighten the four in- stallation bolts evenly and alternately with the socket wrench. R se I Fig. CATUION : Tighten the blade installation bolts carefully when attaching the blades to the tool. A loose installation bolt can be dangerous. Always check to see they are tightened securely. For the correct planer blade setting Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base. Below are some examples of proper and improper settings. (A) Front base (Movable shoe) (B) Rear base (Stationary shoe) Although this side view cannot show it, the edges of the blades run perfectlv parallel to the rear base surface. Cause: One or both blades fails to have surface edge parallel to rear base line. Nicks in at start to rear base line. ~~~&~~ Cause: One or both blade edges pro- at end trudes too far in relation to rear base line. Adjusting depth of cut Depth of cut may be adjusted by simply turning the knob on the front of the tool. Switch action To start the tool, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position. pull the trigger fully, then release it. Fig. 8 CAUTION : Before plugging in the tool, always check to see that the trigger switch actuates properly and returns to the "OFF" position when released. Planing operation First, rest the tool front base flat upon the workpiece surface without the blades mak- ing any contact. Switch on and wait until the blades attain full speed. Then move the tool gently forward. Apply pressure on the front of tool at the start of planing, and at the back at the end of planing. Planing will be easier if you incline the workpiece in stationary fashion, so that you can plane somewhat downhill. The speed and depth Fig. 9 of cut determine the kind of finish. The power planer keeps cutting at a speed that will not result in jamming by chips. For rough cutting, the depth of cut can be increased, while for a good finish you should reduce the depth of cut and advance the tool more slowly. Ch...
