User Manual
•
Always store an idle cutoff saw in a clean dry space
safe from damage or pilferage.
•
Replace the cutoff wheel if worn for maximum
tool performance. Make sure that the wheel is not
chipped or damaged.
• Always keep critical tool markings, such as labels
and warning stickers legible.
• Always replace hoses, couplings and other parts
with replacement parts recommended by STANLEY.
Supply hoses must have a minimum working
pressure rating of 2000 psi/140 bar.
• All hoses must have an oil resistant inner surface
and an abrasive resistant outer surface. Hoses that
conform to SAE100R1A are recommended for most
tool applications.
•
Use only cutoff wheels that meet requirements
of ANSI 87.5. Wheels should be no larger than
10-inches/25.4 em in diameter, 5/32-inch/4 mm
thick with a 1-inch/25.4 or 22 mm arbor hole. Rated
speed must be 5000 rpm minimum.
• Tool repair should be performed by experienced
personnel only.
• Make sure all couplers are wiped clean before
connection.
• The hydraulic circuit control valve must be in
the “OFF” position when coupling or uncoupling
hydraulic tools. Failure to do so may result in damage
to the quick couplers and cause overheating of the
hydraulic system.
HYDRAULIC SYSTEM
REQUIREMENTS
•
The hydraulic system should provide a flow of 10-15
GPM/38-57 LPM at an operating pressure of 1500-
2000 psi/105-140 bar. Recommended relief valve
settings are 2100-2250 psi/145-155 bar.
• The system should have no more than 250 psi/17
bar back pressure measured at the tool end of
the operating hoses. The system conditions for
measurement are at maximum fluid viscosity
or 400 ssu/82 centistokes (minimum operating
temperatures).
•
The hydraulic system should have sufficient
heat rejection capacity to limit the maximum oil
temperature to 140 °F/60 °C at the maximum
expected ambient temperature. The recommended
minimum cooling capacity is 7 hp/5.22 kW at a 40
°F/22 °C difference between ambient temperature
and oil temperature.
• The hydraulic system should have a minimum of
25 micron filtration. It is recommended that filter
elements be sized for a flow of at least 30 GPM/1131
pm for cold temperature startup and maximum dirt
holding capacity.
•
The hydraulic fluid used should have a viscosity
between 100 and 400 ssu/20 and 82 centistokes
at the maximum and minimum expected operating
temperatures. Hydraulic fluids of petroleum base
with anti-wear properties and viscosity indexes over
140 will meet the recommended requirements over
a wide range of operating temperatures.
• The recommended hose size is .625 in/ 16 mm
1.0. up to 50 ft/15 m long and .750 in/20 mm 1.0.
minimum up to 100 ft/30 m long.
PREPARATION CHECKOUT
PROCEDURES
POWER SOURCE
1.
Using a calibrated flowmeter and pressure gauge,
check that the hydraulic power source develops
a flow of 10-15 GPM/38-57 LPM at 1500-2000
psi/105-140 bar.
2. Make certain that the power source is equipped
with a relief valve set to open at 2250 psi/155 bar
maximum.
3. Check that all operating controls and indicators are
easily accessible.
CUTOFF SAW TRIGGER AND SAFETY
CATCH
1. Check that the trigger operates smoothly and is free
to travel between the “ON” and “OFF” positions.
2.
Check that the trigger is set to disengage the cutoff
saw when released.
3. Check that the safety catch on the handle assembly
is operating properly. It should prevent engagement
of the trigger unless the catch is fully pressed down
into the handle slot.
HANDLE
Check that the handle bar is securely fastened to the
motor housing and handle bar strut. Remove any oil
from the handle bar.
WHEEL GUARD
1. Inspect the wheel guard for cracks and other
structural damage.
2. Rotate the guard to ensure that it moves freely on
the wheel-arbor center line.
