MQ-WHITEMAN FS1 CONCRETE SAW — PARTS & OPERATION MANUAL — REV. #3 (04/24/03) — PAGE 23
WARNING
Guards and Covers Check
NEVER operate the saw without blade guards and covers
(Figures 12,13 and 14) 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 12. Mist 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 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.
■
Check the fit of the water hoses about the water manifold.
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.

V-belts and Cover
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 two premium V-belts (14")
and three premimum V-belts (18") that have been aligned and
tensioned by factory personnel. All two V-belts MUST be installed
for proper operation of the saw. Failure to run the saw with less
than two 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 14) to
the saw frame.

Check uniform parallelism (Figure 15) of V-belts and pulley
(sheaves). Use a straight edge or machinists's square
against both pulleys and adjust both pulleys until equally
aligned.
