EMERGENCY LOWERING
If the platform should fail to lower, NEVER
climb down the mast.
Ask a person on the ground to open the Emer-
gency Lowering Valve to lower the platform.
Serial Number 15001 - 21690
This valve is located through a cutout in the power
unit cover on the left side of the mast (Figure 3).
1. Pull the knob out and turn
1
/
4
turn to open the
Emergency Lowering Valve.
2. To close the Emergency Lowering Valve, turn
the knob until it snaps back in.
Serial Number 21691 - Current
The Emergency Control Valve Knob is located at
the rear of the machine. (Figure 3).
1. Open the valve by pulling and holding the
knob.
2. To close the Emergency Lowering Valve,
release the knob.
Once the platform is fully lowered, be certain that the
Emergency Lowering Valve is closed again. The
platform will not elevate if the Emergency Lowering
Valve is open.
NOTE: Optional auxiliary platform lowering
circuit allows operator to lower platform when
power source is interrupted. A warning light on
chassis controls shines when batteries for auxil-
iary platform lowering circuit are low (Figure 3).
Batteries for warning light are located inside
chassis control box.
Safety Interlock Test
NEVER perform this test from the platform.
1. Properly install all four (4) outriggers and level
base.
2. Release the tension on one (1) outrigger by turn-
ing the screwjack counterclockwise, until the
indicator lamp is no longer lit.
3. While standing on the ground activate the control
panel to elevate the platform. Platform should
not elevate.
4. Re-level the base with all four (4) outriggers then
repeat step 2 with another outrigger.
5. Repeat steps 2 , 3 & 4 until all four (4) outriggers
have been tested.
DO NOT use a machine that elevates when the
tension has been released on an outrigger. Ma-
chine must be repaired before using.
Battery Maintenance
Hazard of explosive gas mixture. Keep
sparks, flame and smoking materials away
from battery.
Always wear safety glasses when working
with batteries.
Battery fluid is highly corrosive. Rinse
away any spilled fluid thoroughly with
clean water.
Always replace battery with UpRight battery
or manufacturer approved replacement
weighing at least 52 lbs. (23.6 kg) each.
Check battery fluid level daily, especially if
work platform is being used in a warm, dry
climate.
If electrolyte level is less than
3
/
8
in. (10 mm) above
plates add distilled water only. DO NOT use tap
water with high mineral content, it will shorten
battery life.
Keep terminals and tops of batteries clean.
Refer to the Service Manual to extend battery life
and for complete service instructions.
AFTER USE EACH DAY
1. Ensure that the platform is fully lowered.
2. Park the machine on level ground, preferably
under cover.
3. Secure against vandals, children or unautho-
rized operation by turning the Key Switch to
OFF and remove the key.
