FCG1 CONCRETE SAW — GUARDS, COVERS AND V-BELTS
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.
Figure 5. Blade Guard
CHECK the following on the"blade guard" (Figure 5):
■ 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.
■ Check that the spring tensioned front cover of the guard is
firmly seated with the rear section of the guard, and there are
no gaps. NEVER lift the blade guard while cutting.
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 and the V-belt
as outlined on page 19.
CAUTION CAUTION CAUTION
CAUTION CAUTION
NEVER attempt to check
the V-belt with the engine

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 6) to
the saw frame.
Figure 6. V-Belt Cover
2. Check uniform parallelism (Figure 7) 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 7. 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 8.
