PAGE 24 — MQ-WHITEMAN FS2/FS2SP CONCRETE SAW — PARTS & OPERATION MANUAL — REV. #2 (06/26/06)
WARNING
Guards and Covers Check
NEVER operate the saw without blade guards and covers
(Figures 14, 15 and 16) in place. DO NOT operate with the
front of the blade guard raised. The blade exposure cannot
exceed 180 degrees during operations. Adhere to the safety
guidelines of the American National Standards Institute
(ANSI) B7.1 and B7.5.
Figure 14. Blade Guard
CHECK the following on the "blade guard":
■
Check to ensure the capacity of the blade guard matches the
diameter of your diamond blade.
■
Check that the guard seats firmly upon the bayonet fitting of
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.
■
Check the fit of the water hoses about the two water manifolds
(14" guard). NEVER lift the blade guard while cutting.
■
Check that the flood water tubes and water jets are clear and
open. Test the water supply for pressure and flow (to both
sides of the blade) before sawing operations.
CHECK the following on the "blade flange cover":
■
Check that the flange cover seats firmly upon the bayonet
fitting of the saw frame prior to operation.
■
This flange cover is to be in place when cutting from either the
right or left side of the saw.

CAUTION:
NEVER attempt to check the V-belt with the engine running
because severe injury can occur. Keep fingers, hands, hair and
clothing away from all moving parts.
V-belts Alignment and Tensioning
This concrete saw is equipped with four premium V-belts that
have been aligned and tensioned by factory personnel. All four
V-belts MUST be installed for proper operation of the saw. Failure
to run the saw with less than four belts may damage the saw or
equipment.
Use the following procedure to check the alignment of V-belts:
1. Remove the bolts that secure the V-belt cover (Figure 16) to
the saw frame.

2. Check uniform parallelism (Figure 17) of V-belts and pulley
(sheaves). Use a straight edge or machinists's square against
both pulleys and adjust both pulleys until equally aligned.
