Instruction manual

Speed Control of Blade Movement:
The downstroke speed of the blade is controlled by the Hydrocheck, P/N B3P146 or P/N B3P148 located next to
the main drive Cylinder, P/N B3P306 or P/N B3P308. The Upstroke Control Valve, P/N B3P60 is located in
port No. 5 of the main control Valve, P/N B3P73. Simply rotate head of valve and adjust in to slow down, or
out to speed up. If not equipped with a hydrocheck, the down speed is regulated by a flow control valve (P/N
B3P60) near the base of the main cylinder.
Preventative Maintenance:
The 400 Series machines are relatively easy machines to operate and maintain. Following is a weekly check list
of General Maintenance items. The best preventative maintenance advise is to CLEAN THE MACHINE DAILY,
especially around the pivot points on the machine.
Lubrication and Adjustments of Bearings:
NO LUBRICATION OR ADJUSTMENTS ARE REQUIRED. All CTD cut-off saws are assembled using
sealed, prelubricated ball bearings. The spindle and pivot assembly are constructed using preloaded belleville
springs. These springs eliminate the need for adjustments of bearings and also greatly increase the life of the
bearings.
General Maintenance Weekly Check List:
Always disconnect electrical power and air supply.
1. Keep machine clean—especially around pivot bracket and pivot bearings.
2. Blow off and clean around the cylinder
3. Check Air Filter Bowl for water and condensation build up.
4. Remove any scrap pieces and dust build up from inside floor stand.
5. Check monthly:
A. For excessive belt wear
B. Make sure motor pulley set screws are tight.
Repair and Service:
Always use CTD factory authorized replacement parts and consult factory before making any repairs or
adjustments which may be unclear.
Fence Alignment and 45° Angle Adjustment of Blades:
All machines are preset at the factory for perfect 90° and 45° mitre cuts. If any adjustments are necessary:
1. Check alignment of fences—left to right as shown in Diagram “E” on Page No. 7. Use a two foot steel scale
or quality precision straight edge and lay flat on table base. Butt edge against fence bracket and long mea-
suring gage (if purchased). Touch the outside corner of the straight edge. If one side of the straight edge
pulls away from the fence, then the long fence gage is not in alignment with the Right Fence, P/N 400M05.
2. Loosen 3/8-16 lock nut on Left Fence Bracket, P/N 41C04L and Fence Support Angle, P/N BF16. Clean
all surfaces of dirt or dust, and re-assemble as before (see Diagrams “A” & “B” on Pages No. 3 & 4).
3. Re-align right fence to left fence with your straight edge. Once you are sure both fences are in alignment,
you now have a reference point to check your 45° mitre.
