PAGE 26 — MQ SP2 SLAB SAW — PARTS & OPERATION MANUAL — REV. #7 (09/08/06)
DO NOT attempt to operate the saw until the Safety, General
Information and Inspection sections have been read and
understood. Depending on engine manufacturer, operating
steps may vary. See engine operating manual.
MQ SP2 SLAB SAW — ELECTRIC START-UP (20HP HONDA ENGINE)
1. Ensure the diamond blade has been mounted correctly and
that it is raised above the surface you are about to saw.
2. For wet cutting operations, ensure the water tank is filled to
capacity (5 gallons). Connect the water tank hose to the water
system brass fitting on the rear of the console (Figure 18) and
test for adequate water flow to the diamond blade before
operation.
3. If operating the SP2 slab saw in
cold weather conditions
,
skip this step and proceed to step 4. Place the
Choke Lever
(Figure 25) in the
OPEN
position. Skip to step 5.
The CLOSED position of the choke
lever enriches the fuel mixture for
starting a COLD engine. The OPEN
position provides the correct fuel
mixture for normal operation after
starting, and for restarting a warm
engine.
