Special Set-Up Procedure (continued)
• To reduce the risk associated with mechanical and electrical hazards:
− Turn electrical and air supply off and disconnect before performing any adjustments,
maintenance or servicing the machine or taping heads
Box and Machine Bed Height Range – Refer to Figure 13-11
Moving the outer columns up one set of mounting holes increases the maximum box size handled by the
700rks case sealer and decreases the minimum machine bed height.
IMPORTANT – When raising the column, the existing Safety Plates (2) must be replaced by a new Safety Plate
(included in the parts kit) as shown in Figure 15266.
Note – This also increases the minimum box height from 120mm [4.8 inch] to 170mm [6.8 inch].
To move the outer columns up one set of mounting holes:
1. Lift the upper taping head/drive assembly up and place a 200 - 250mm [8 - 10 inch] block at the front and rear
of the upper drive assembly. Important – Blocks (front and rear) must be same height in order to keep upper
drive assembly parallel with machine bed. Also, block both columns up with solid spacers between outer
columns and fl oor. See Figure 13-11A.
2. Remove and retain the six screws and plain washers that fasten each column to the frame - Figure 13-11B.
3. Lift the outer columns up one set of mounting holes, and place spacers between the blocks on the fl oor and
each column. See Figure 13-11C.
• To reduce the risk associated with muscle strain:
− Use the appropriate rigging and material handling equipment when lifting or repositioning this equipment
• To reduce the risk associated with impact hazards:
− Always use appropriate supporting means when working under the upper drive assembly
4. Install and tighten the six (6) screws and plain washers in each column that were removed in Step 2. Turn on
air supply, raise and lock upper drive assembly in fully raised position and remove all blocks and spacers.
If desired, the bed height can now be decreased to 570mm [22.5 inch] by adjusting legs upward.
