HAND SAW OPERATING PROCEDURES
Blade Mounting
Be certain that you have correct diamond blade for the application. Contact your authorized servicing
dealer for the correct specification. Ensuring that the correct blade is used will greatly increase
performance and durability of blades resulting in cost savings.
The blade shaft flanges and arbor must be inspected for damage and cleaned before mounting the
blade. If damaged, replace worn or broken parts. Inspect blade for damage to arbor hole and flange
area before attempting to mount blade.
Make sure the arrow on the blade is pointing in the proper direction of rotation. The drive pin in the
outer blade flange must go completely through the blade into the matching hole in the inner blade
flange. Using the wrench provided, tighten flanged nut securely (Approximately 30 ft. lbs.). Note that
the flanged nut has left hand threads, which tighten by turning counter clockwise.
BEFORE SAWING
Do not use conventional (wet) diamond blades without water. You must have 2.5-5 gallons of water per
minute flowing over the blade for proper cooling and ensuring proper blade life. For wet sawing, be
sure to spray holes in the water manifold are open and each side of the blade receives adequate
water flow.
Test your water supply for pressure and flow rate before starting saw.
Mark the cutting line clearly so that the saw operator can follow the line without difficulty.
CUTTING THE LINE
With the saw blade above the cut, squeeze the trigger to start the water flowing and allow the saw
blade to reach the desired speed before the blade contact the surface. Pivot the saw on the front roller
and slowly lower the blade into the cut line. Do not exceed more than 2.00”cutting depth per pass. At
the end of the cut, pivot the saw on the front roller and raise the blade until it clears the cut, then
release the trigger. Allow the blade to come to a stop before setting down. Increase the depth of cut
by 2.00”by increasing the blade diameter and follow the previous cut line. This procedure is known as
step cutting. Continue with this procedure in 2.00”increments until you have reached your desired
depth of cut.
When cutting vertical wall cuts, start from the top working down. Make the first pass shallow, being extra
careful not to go off the cut line. Increase cut depth with each pass following the previous cut. If the first
cut starts to wander, stop sawing and correct the cut by plunging a straight and deeper cut before and
after the error. After this go back with the blade cutting twice the depth of the error and cut between
the two using the blade to guide past the error.
Horizontal cuts are the most difficult to make correctly. Before starting the horizontal cut, make sure
there is enough room for you to work without reaching beyond your area of control. When sawing from
a lift or scaffolding, always figure the amount of hoses you will need to tie off. Leave only what you
need for the job.
HAND SAW MAINTENANCE INSTRUCTIONS
Check all hydraulic hoses and connections daily. Any leakage of hydraulic fluid will require immediate
retightening or replacement of parts. When replacing hydraulic components use only parts with proper
pressure ratings. WARNING! Before disconnecting hoses, be sure to relieve all pressure. Do not use
damaged or non-rated hoses or fittings.
Tighten fasteners occasionally. Nuts and bolts may become loose particularly after the first few hours of
use.
Check hydraulic supply for correct pressure and flow rate that is appropriate for your saw, all saw have
a GPM rating decals.
Clean saw by removing all accumulated dust or slurry after use. If allowed to dry, the slurry will harden
and could impair efficiency and performance.
Inspect the blade guard frequently for damage and wear. Concrete slurry can erode the aluminum in
the blade guard. If any portions of the blade guard measures less than 3/16” (.187) discard unit.
