MAINTENANCE WARNING: When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage. WARNING: Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could result in objects being thrown into your eyes, resulting in possible serious injury. WARNING: Before performing any maintenance, make sure the tool is unplugged from the power supply and the switch is in the off ( O ) position. Failure to heed this warning could result in serious personal injury. GENERAL MAINTENANCE Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, oil, grease, etc. WARNING: Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. After using the drill press, clean it completely and lubricate all sliding and moving parts. Apply a light coat of ­automotivetype paste wax to the table and column to help keep the surfaces clean. LUBRICATION  Lower spindle to maximum depth and oil moderately once every three months.  Oil the column lightly every two months.  If cranking becomes difficult, grease gear rack lightly. The ball bearings in the tool are permanently lubricated. MOTOR/ELECTRICAL The induction motor is easy to maintain but must be kept clean. Do not allow water, oil, or sawdust to accumulate on or in it. The sealed bearings are permanently lubricated and need no further attention. HEAD ASSEMBLY AND MOTOR HOUSING Frequently blow out any dust that may accumulate inside the head assembly and/or motor housing. PULLEYS See Figure 23, page 22. Should you feel an unusually high level of vibration, the pulleys may not be tightly secured on the motor and/or spindle shafts. To make sure the pulleys are properly seated and tight, locate the set screw on each of the pulleys. Tighten each set screw with the hex key. GEAR RACK Periodically lubricate the worm gear and gear rack in order to keep the vertical movement smooth and to help prolong the life of the drill press. BATTERIES Check the laser batteries regularly to avoid deterioration. Remove the batteries if you will not be using the laser for an extended time. 15 - English
