    ASSEMBLY INSTRUCTIONS NOTE: For clarity, the Grinder is shown on the following pages without the optional carriage bellows installed. UNPACK THE CARTONS NOTE: Before you install the machine, read the following assembly procedure completely. Then study "Getting to Know Your Bedknife Grinder" in the Operators Manual. Use care when unpacking.
  • Page 7 ASSEMBLY INSTRUCTIONS (Continued) LOCATE AND LEVEL THE GRINDER Set the Grinder on a level concrete floor, on a single uncracked slab of concrete. If the unit must be located near a wall, allow adequate space for operating and servicing. Refer to FIG. 3 for recommended and alternate locations near a wall.
  • Page 8 ASSEMBLY INSTRUCTIONS (Continued) APPLY POWER BEFORE YOU APPLY POWER TO THE GRINDER, REFER TO THE "IMPORTANT GROUNDING INSTRUCTIONS" ON PAGE 9. 115 Volt Model Only. Plug the control box power cord into a standard 115V AC 15-amp grounded receptacle. See FIG. 7. FIG.
  • Page 9 ASSEMBLY INSTRUCTIONS (Continued) FOR 220 V 50 or 60Hz applications Product No. 6700951 should be ordered. 6700951 includes a 2 KVA 220 Volt Step Down to 110 volt 50/60 Hz transformer which is prewired. The wiring diagram is shown in FIG. 8. The power cord has no connector.
  • Page 10 ASSEMBLY INSTRUCTIONS (Continued) Actuator Mounting INSTALL THE OPTIONAL Screw (under the rubber CARRIAGE BELLOWS (if ordered) splash guard) Optional carriage bellows are available to keep excess grindings, dirt, etc. out of the carriage assembly. To install the two bellows: 1. Remove the left and right outside leg panels. Actuator Bar Assembly 2.
  • Page 11 ASSEMBLY INSTRUCTIONS (Continued) INSTALL THE COOLANT TANK Assemble the Coolant Tank as outlined in the instructions (Part No. 7467909) in the coolant tank carton. Center the Tank under the Grinder. Install the 1" I.D. drain tubing over the barbed end of the plastic adapter on the coolant tray drain.
  • Page 12 ASSEMBLY INSTRUCTIONS (Continued) CHECK THE CARRIAGE TRAVERSE Move the proximity switch assemblies to about 12" [300 mm] from the ends of the machine, and tighten their knobs. Visually check that the grinding head will be able to traverse to both sides of the machine without contacting any components.
  • Page 13 MAINTENANCE DAILY MAINTENANCE IS SPECIFIED ON PAGE 4 OF THE OPERATOR'S MANUAL, AND IS TO BE PERFORMED BY THE OPERATOR. LISTED BELOW ARE PERIODIC MAINTENANCE ITEMS TO BE PERFORMED BY YOUR COMPANY'S MAINTENANCE DEPARTMENT: 1. Lift the bellows, (See FIG. 14) if used, and wipe off the traverse driveshaft and the bearing rails monthly.
  • Page 14 MAINTENANCE (Continued) LUBRICATION Actuator and Linear Bearings Do the following every six months (or more often if the linear actuator seals are squeaking): 1. Thoroughly clean the carriage rails, drive shaft, and shaft seals. Wipe the shafts and seals thoroughly with a clean rag.
  • Page 15 MAINTENANCE (Continued) CLEANING AND MAINTENANCE GUIDELINES FOR POLYCARBONATE WINDOWS Cleaning Instructions DO NOT USE GASOLINE Adherence to regular and proper cleaning procedures is recommended to preserve appearance and performance. Washing to Minimize Scratching Wash polycarbonate windows with a mild dish washing liquid detergent and lukewarm water, using a clean soft sponge or a soft cloth.

Only remove the bearings from the actuator block. 1. Crank the horizontal handwheel until the carriage is Actuator Bar Assembly all the way forward (toward the operator position).
  • Page 17 ADJUSTMENTS (Continued) TO REPLACE THE LINEAR ACTUATOR BEARINGS Hold the drive shaft from rotating while you check the pulling force. 8. Slide the carriage over the actuator, and line up the hole in the carriage with the tapped hole in the top of the actuator block.
  • Page 18 ADJUSTMENT (Continued) TO REPLACE THE CARRIAGE LINEAR BEARINGS NOTE: Set a small bench or table near the center front of the machine for use in the following procedure. 1. Remove the optional carriage bellows (if used) from the carriage. Remove the actuator release lever from the linear actuator.
  • Page 19 ADJUSTMENTS (Continued) TO REPLACE THE CARRIAGE LINEAR BEARINGS 7. Attach the three linear bearing pillow blocks loosely to the bottom of the carriage, with their tension adjustment Rear Pillow Blocks screws (FIG. 23) facing outward. 8. Clean the carriage rails. NOTE: The two rails are interchangeable and are also reversible (end-for-end).
  • Page 20 ADJUSTMENT (Continued) TO ALIGN THE MOTOR SHAFT AND DRIVE SHAFT There must be 0.12 to 0.50 in. (3.0 to 12.7 mm) end clearance between the traverse motor output shaft and the drive shaft, inside the flexible coupling (FIG.27). To prevent drive shaft "whipping" at higher traverse speeds, the two shafts must be aligned so they are concentric within .010 in.
  • Page 21 ADJUSTMENT (Continued) TO ADJUST THE PROXIMITY SWITCHES For the proximity switches to work properly and reverse the direction of the carriage at each end of a traverse, a distance of 3/16 in. +/- 1/32 [4.75 mm +/ - 0.75] must be maintained between the top of the switch and the actuator bracket on the bottom of the carriage.
  • Page 22 ADJUSTMENTS (Continued) TO ELIMINATE CARRIAGE INFEED BACKLASH If there is backlash in the carriage infeed handwheel (FIG. 35), there are two adjusting points to check: 1. Conical washers behind the shaft adjusting nut: A. Unscrew the shoulder bolt. B. Hold the horizontal handwheel, and turn the shaft adjusting nut counterclockwise until the conical washers are touching each other.
