Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until drill press is assembled and running properly. 6.2 GROUNDING INSTRUCTIONS This tool must be grounded.
Make sure incoming current matches power requirements of the drill. When machine is connected properly, spindle turns clockwise in a conventional drilling rotation. If spindle does not turn clockwise, disconnect drill from power supply and reverse any two of the three power leads (except green ground wire). Figure 7-1: table adjustments 7.2 Tool installation and removal 1. Disconnect machine from power source. 2. Thoroughly clean inside of spindle with a soft dry cloth.
7.4 Coolant pump The coolant system should be filled with 2 gallons of a cutting coolant. Fill by pouring coolant into base of machine. Add coolant in the same manner when coolant is low. To drain coolant, remove hex cap screw located on lower backside of base. Follow all coolant manufacturer’s instructions for safety, mixing and disposal. Make sure drain hose has good, tight connection into table and that coolant flows into base.
Speed range handle (I): Selects high or low speed range. See sect. 4.0 for ranges. Stop spindle before moving handle. 7. 9.2 Manual drilling Spindle must be stopped before attempting to adjust speed range handle. Failure to comply may damage speed adjustment mechanism. Downfeed handle (J): Lowers quill/spindle. Engages powerfeed or manual fine feed when moved away from head. Can be pushed toward head to disengage power feed at any time. 1. Set switch (H) to drill mode. 2.
5. Pull downfeed handle (J) away from head to engage powerfeed. 6. When set depth is reached, downfeed handle will disengage and spindle will retract. Spindle will continue to rotate. 9.6.4 Speeds for high speed steel drills Material Alloy Steel — 300 to 400 Brinell Stainless Steel Automotive Steel Forgings Tool Steel, 1.2C Steel, .4C to .5C Mild Machinery Steel, .2C to .
10.2 Motor replacement Disconnect electrical power to drill press to avoid possibility of inadvertent operation and exposure to potentially lethal voltage levels. 1. Disconnect machine from power source. 2. Follow steps under sect. 10.1 to remove drive motor. 10.3 Lubrication See Table 4 for lubrication points and frequency. Figure 10-1: oil fill tube Oil fill tube: a. 10.4 Additional servicing Periodically check oil level in sight gauge (A, Figure 10-1). b.
