If you do not have this equipment, you can not service this tool. Hypot testing is a safety test required by Underwriter’s Laboratories. It basically ensures that there are no live metal parts exposed on the product. This condition could occur if, for instance: 1. A housing screw went through a wire. 2. A wire was stripped back too far and the bare wire contacted a bearing or the driveshaft. 3. A wire was damaged and came into contact with a bearing or the driveshaft. This is a very serious safety issue so please take care to test the tool as specified below. The tool is to be Hypot tested at 3000 VAC for I second between: A. Both power cord prongs and the chuck with the power switch in the ON position. B. Between the power cord prongs and all of the housing screws with the power switch in the ON position. The maximum allowable current is 0.SmA. REPAIR The following are specific instructions for repairing the 8800ES drill. For a list of available service parts and an exploded-view product drawing, please refer to the last page of this manual. These repair instructions start with the very basic repairs such as replacing a chuck and progress to the more complicated such as replacing a housing. They are done this way so all of the information does not have to be repeated. For this reason you may want to read the entire instruction before proceeding with one of the more complicated repairs. CHUCK REMOVAL I INSTALLATION Removal 1. Open chuck jaws to maximum capacity. 2. Remove retaining screw on tool by turning it in a clockwise direction (screw has a left-hand thread). 3. Insert the shorter end of a 1/4” or greater hex key into chuck and tighten. FOR MODEL NO. 8800ES 4. Place tool on its side and hold firmly. 5. Using a wooden mallet strike the longer end in the clockwise direction. Installation 1. Screw the chuck on by hand as far as it will go. 2. Insert screw (left-hand thread), and tighten screw securely. 3. Tighten the chuck around the shorter end of a 1/4” or larger hex key, then strike the longer end in the clockwise direction with a wooden mallet while holding down the tool securely. 4. Tighten the screw once again by turning in a counterclockwise direction. BRUSH REMOVAL I INSTALLATION Removal 1. Remove brush cap using a flat-head screwdriver. 2. Remove brush assembly from the brush holder. Installation I. Installation is the reverse of the removal instruction above. GEARBOX REMOVAL I INSTALLATION Currently, the gearbox components are not individually available, and in the event of a failure, the entire gearbox must be replaced. The procedure for removing / installing the gearbox is as follows: Removal 1. Remove the chuck as described above. 2. Remove the brush caps and take out the brushes. The brushes should always be removed before disassembling the housing. 3. Remove the (8) housing screws and remove the right housing half. While removing the right housing half, disconnect the yellow brush lead from the brush holder. This can usually be disconnected with your fingers. If not, a needle-nose pliers will suffice. 4. Remove the chuck shroud. 5. Lift up the gearbox so that the motor assembly tips upward. Once the gearbox is above the left housing half, pull it away from the motor so the input shaft pulls out of the motor coupling. Installation 1. Remove the armature while leaving the field in place. In order to remove the armature, you will have to tip up the field so that the fan clears the housing. 2. Ensure that there is grease in the motor coupling and that the o-ring is in place in the end of the coupling. If grease must be added, a light film of any moly based grease will be adequate. 3. Insert the gearbox into the coupling assembly. 4. Tip up the field and slide the gearbox/armature assembly into location. 5. Reseat the field and make sure the armature spins freely. 6. Remainder of assembly is the reverse of the removal procedure above. MOTOR COUPLING REMOVAL I INSTALLATION Removal 1. Remove the chuck as described above. 2. Remove the top housing half and gearbox as described above. 3. Remove the armature from the tool as described above. 4. The coupling is press fit onto the knurled end of the motor shaft. Remove the coupling using an arbor press or other suitable press. With the armature pointed upward, the coupling should be held from the bottom side and the armature pressed down. Installation 1. Install a light film of moly based grease to the inside of the coupling - both in the large and small diameter bores. 2. Remainder of the installation is the reverse of the removal instruction above. NOTE: It is very important that the coupling be lined up properly during installation. Failure to install the coupling straight will result in tool vibration. MOTOR REMOVAL I INSTALLATION Removal 1. Remove the chuck as described above. 2. Remove the top housing half and gearbox as described above. 3. Remove the armature from the tool. 4. Disco...
