straighter than competitive designs. In addition the machine features a vacuum port,
and dust Bellows to help keep air bore dust down to when compared to other
machines. The up cut blade rotation is utilized to help the vacuum system extract
the cutting particles.
Joint Clean Out Considerations:
1. Verify the voltage and circuit Amperage. See section
E. Electrical Connections
GC25E UP
for additional details. Connecting any electrical product to the
incorrect power source can result in product failure covered under any warranty.
2. If using an extension cord insure that it meets the length and gauge requirements
as stated in section
E. Electrical Connections GC25E UP
. Failure to use the
correct size extension cord can result in circuit breaker tripping, poor
performance, or motor damage which is not covered under any warranty.
3. Cut no deeper that 1-1/2” per pass for the best performance. If cutting deeper
per pass the forward cutting speed will need to be reduced. Do Not cut more
than 1-3/4” deep per pass. Diamond Blades will cut faster and last longer if
shallower cuts are made, aka Step Cutting.
4. Let the Blade cool off. Every few minutes stop the forward movement of the
machine and let the blade cool: cut for 2 to 5 minutes let the blade cool for 30
seconds. The blade will last longer and it will cut faster.
5. Verify that the blade is correct for the material being cut. Incorrect blade
specifications will create more friction which will result in the electric motor
drawing more amperage and may trip circuit breakers or over heat the electric
motor. It is best to use diamond blades with low diamond concentration and a
soft bond with ALL electrical powered saws. Use of hard bonded blades with
high diamond concentrations may result in motor damaged and is not covered
under any warranty.
6. When cutting concentrate on keeping the machine in the middle of the cut not on
the cutting speed.
7. Do not cut into the Backer Rods. Most Backer Rods are made of steel which will
result in tripping of breakers, slow cutting speeds, and or over heating of the
electric motor.
8. Let the GC25E UP work for you. As you push it harder the motor will draw more
amperage which will over time trip the breaker. The motor with a medium
working load will pull around 13A and will run with no problem.
a. Do not force the machine, unlike the typical hand held tools typically used
for this application the GC25E UP does not need to for forced through the
joint.
b. When cutting do not over load the machine. The machine will sound like it
is working harder before the breaker trips. When the motor starts to labor
let off of the feed speed
