your possession, hydraulic oil is clean, hydraulic tank is 3/4 to 7/8 full, and the machine has been pre-run to
warm the hydraulic oil. To correctly check relief valve pressure, gauge MUST be installed correctly.

WARNING
!
The relief valve is typically located internally in the valve bank. Do not adjust the relief valves above the
­specified­psi­(bar).­The­relief­valve­system­is­a­simple­spring­tension­design­but­small­pieces­of­debris­can­
stick the valve partially open which weakens the hydraulic power. The relief as well as hydraulic oil, and
suction screen must be kept clean.
CHECKING HYDRAULIC PRESSURE
1.­ Make­sure­all­the­controls­are­in­the­off­position.
2. Install pressure gauge into the test port of the function that needs to be checked, see Figure 2.
3. Start engine and adjust engine to full throttle.
4. Engage the control switch so that the cylinder of the function that needs to be checked, bottoms out and
then read the pressure gauge.
5. Adjust relief if necessary. Turn the relief clockwise to increase pressure and counter- clockwise to decrease
the pressure.
NOTE: To set the auxiliary pressure: turn the blade relief all the way in, set the auxiliary pump relief, then
reset the blade relief. Main relief pressure is not adjustable.
CHECKING HYDRAULIC FUNCTION PRESSURE
CUSTOM MANIFOLD VALVE
1.­ Make­sure­all­the­controls­are­in­the­off­position.
2. Install the cutter wheel lock pin
3. Install pressure gauge into the test port, see Figure 3.
4. Start engine.
5. Place the cutter wheel on the ground.
6. While engine is at full throttle, momentarily engage the cutter wheel.
7. Adjust relief if necessary. Turn the relief clockwise to increase pressure and counter- clockwise to decrease
the pressure.
CHECKING CUTTER WHEEL PRESSURE
1.­ Make­sure­all­the­controls­are­in­the­off­position.
2. Install pressure gauge into the test port, see Figure 1 or Figure 2, depending on which valve is in your
machine.
3. Start engine.
4. Adjust engine to full throttle.
5. The pressure reading is used to trouble shoot the machine.
CHECKING PUMP CHARGE PRESSURE
1.­ Make­sure­all­the­controls­are­in­the­off­position.
2. Install pressure gauge into the test port, see Figure 1.
3. Start engine and adjust engine to full throttle.
4. Engage the control switch so that the cylinder of the function that needs to be checked, bottoms out and
then read the pressure gauge.
5. Adjust relief if necessary. Turn the relief clockwise to increase pressure and counter- clockwise to decrease
the pressure.
NOTE: To set the main pressure: turn the cutter wheel lift relief 2 turns in, set the main relief, then turn the
cutter wheel lift relief 2 turns out.
