SP1G CONCRETE SAW • OPERATION MANUAL — REV. #3 (09/07/17) — PAGE 19
INSPECTION
BLADE GUARD
Figure 4. Blade Guard
Check the following on the blade guard (Figure 4):
Ensure the capacity of the blade guard matches the
diameter of your diamond blade.
Check that the guard is bolted firmly upon the saw frame.
V-BELT CHECK
A worn or damaged V-belt can adversely affect the
performance of the saw. If the V-belt is defective or worn,
replace the V-belt as outlined in the maintenance section.
WARNING
NEVER
operate the saw without blade
guards and covers in place.
DO NOT
operate with the front of the blade guard
raised. The blade exposure cannot exceed
180 degrees during operation. Adhere to the
safety guidelines of the
American National
Standards Institute (ANSI) B7.1 and B7.5.
CAUTION
NEVER
attempt to check the V-belt with the
engine running. Severe injury can occur.
Keep fingers, hands, hair and clothing
away from all moving parts.
V-belt Alignment and Tensioning
This concrete saw is equipped with a premium V-belt that
has been aligned and tensioned by factory personnel. The
V-belt must be aligned and tensioned for proper operation
of the saw.
Use the following procedure to check the alignment of
V-belt:
1. Remove the bolts that secure the V-belt cover (Figure 5)
to the saw frame.
Figure 5. V-Belt Cover
2. Check uniform parallelism (Figure 6) of V-belt and
pulley (sheaves). Use a straight-edge or machinist's
square against both pulleys and adjust both pulleys
until equally aligned.
Figure 6. Pulley Alignment
3. Check V-belt tension by using a tension meter
(6.0 – 9.0 lbs.) against the inside belt at a mid point
between the two pulleys, or by deflecting the center
belt at a mid point 3/8" (10 mm) to 1/2" (13 mm). See
Figure 7.
