PROBLEM
PROBABLE CAUSE
REMEDY
Scrub deck will not lower
(Cont.)
1. Low hydraulic oil level
2. Scrub deck obstructed
3. Damaged valve and/or coil
4. Damaged check valve
5. Damaged deck cylinder
1. Inspect the oil level in the reservoir and
add oil until visible in the sight gauge
2. Remove obstruction.

Check the continuity of SV3 coil on the
cylinder control valve. With a voltmeter
across the harness leads to the coil,
activate the scrub deck lift switch. With
the switch in the "LOWER" position, the
meter should read 12volts. If the voltage
reading is 0, inspect the harness and
scrub deck switch and replace as
required. If the voltage reading is 12,
inspect SV2. Repair or replace the valve
and/or coil as required.
Install a pressure gauge as port "C2" on
the cylinder control manifold. With the
machine on and the "HEAVY SCRUB"
switch activated, the gauge should read
200 ± 25 PSI. If the reading is below
175 PSI, inspect the O-ring on SV3, SV4,
and SV5 and repair or replace the
cartridges as required. If the solenoid
valves appear functional and the
condition remain, replace the check
valve (CV1).
If the condition remains after the above
efforts, repair or replace the scrub deck
cylinder.
