Powermatic 15HH - Manual (Page 10)

10
This machine must be grounded. Grounding
provides a path of least resistance to help divert
current away from the operator in case of
electrical malfunction.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the machine.
Extension Cords
The use of an extension cord is not
recommended for this machine, but if one is
necessary make sure the cord rating is suitable
for the amperage listed on the machine's motor
plate. An undersize cord will cause a drop in line
voltage resulting in loss of power and
overheating.
The chart in Figure 11 shows the correct size
cord to use based on cord length and motor
plate amp rating. If in doubt, use the next
heavier gauge. The smaller the gauge number
the heavier the cord.
Adjustments
Tools required for assembly:
10, 12 and 17mm open-end wrenches
3, 5 and 6mm hex wrenches
0.2” (0.5mm) feeler gauge
straight edge
gauge block
cross-point screwdriver
Disconnect machine from
power source before making any
adjustments (except feed rate).
Belt Tension
Inspect the tension of the belts frequently during
the first few times you use the planer. Belts often
stretch during this trial period. If they require
tightening, proceed as follows:
1. Remove the belt guard and the rear panel.
2. Loosen the bottom nut on the motor
adjustment screw (Figure 12) with a 17mm
wrench.
3. Turn the top nut on the adjustment screw to
lower the motor plate, which will increase
the belt tension.
4. Proper tension is achieved when there is
slight deflection in the belt midway between
the pulleys, using moderate finger pressure.
5. Tighten the bottom nut on the adjustment
screw (Figure 12).
