SP213H20A / SP2S20H20A SAWS — OPERATION AND PARTS MANUAL — REV. #1 (05/17/10) — PAGE 25
Guards and Covers Check
NEVER operate the saw without blade
guards and covers (Figures 13 and14) in
place. DO NOT operate with the front of the
blade guard raised. The blade exposure
cannot exceed 180 degrees during operations.
Figure 13. 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 in the sides of the blade
guard. NEVER lift the blade guard while cutting.
■ Check that the flood water tubes 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 Covers
V-belts Alignment and Tensioning
This saw is equipped with 3 premium V-belts (3 for 13HP models,
4 V-belts for 20HP models) that have been aligned and tensioned
by factory personnel. All V-belts MUST be installed for proper
operation of the saw. Failure to run the saw with less than the
required number of belts may damage the saw or equipment.
Use the following procedure to check the alignment of
V-belts:
INSPECTION -GUARDS, COVERS & BELTS
Figure 15. V-Belt Cover
Figure 16. V-Belt Parallelism
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.
1. Remove the bolts that secure the V-belt
cover (Figure 15) to the saw frame.
2. Check uniform parallelism (Figure 16) of
V-belts and pulley (sheaves). Use a straight
edge or machinists's square against both
pulleys and adjust both pulleys until
equally aligned.
