Introduction
2-1 GENERAL DESCRIPTION
The XLB-4232 DC Boom Lift is designed and manufactured for positioning personnel
with their tools and equipment at overhead work locations. The rated work basket load
capacity is 300 lbs. for the XLB-4232. Basket elevation is by two hydraulic cylinders
acting on the boom sections. A hydraulic powered motor and worm gear rotates the boom
360° around a vertical axis. The hydraulic power unit includes a reservoir, pump, and
control valves.
On the battery powered (DC Model) boom lift, dual 24 Volt, 39 Amp, one horsepower,
DC electric motors drive the hydraulic pump. The DC motor is powered by four 6 Volt
DC, 245 Amp-hour, deep charge batteries connected in series. A 40 amp, automatic, onboard battery charger is provided for recharging the batteries at the end of each work
period.
Two control panels use directional selector switches and hydraulic valves to control the
direction and speed of boom lift and rotation. One set of operator controls is provided for
ground operation and another set is provided for operation from the basket. Elevation and
rotation controls are operational only when the moving boom section is within a
programmed safe operating zone. Only one boom motion is permitted at a time, and only
as long as the boom is within the safe operating zone. When a selected boom motion
reaches a safe operating limit, the motion ceases and another motion must be selected
within the safe operating zone.
Outrigger and wheel position interlock safety switches prevent lifting operations until the
four outriggers are properly deployed and the full weight of the boom lift is loaded onto
the outriggers.
Boom elevation speeds are selected from low to high by a toggle switch. A hydraulic hose
failure at either retract-cylinder port will cause a velocity fuse to close and stop the return
oil flow. It is strongly recommended that no one adjust or tamper with these safety
devices. If service is required, please notify Bil-Jax for detailed instructions.
Emergency lowering of the basket is by a manual valve on the base of the lift cylinder.
Pushing in and turning 1/4 turn manually retracts the upper boom lift cylinder. The boom
may need to be manually rotated to a clear area before lowering.
The boom lift cylinders will not rust or corrode during storage since the cylinder rod is
fully immersed in oil. It is important that the cylinder rods be kept clean and undamaged
for the protection of the cylinder head packings.

3-5 BATTERY RECHARGE (DC MODEL ONLY)
The DC boom lift batteries should be recharged after each 8-hour work shift or more
often if needed. When the boom lift is not in use, the batteries should be recharged at least
once per week.
The normal charge time is 10 to 12 hours. If the battery charge is extremely low, a full
recharge may take up t o 24 hours.
Recharge the DC boom lift batteries as follows:
WARNING
Recharge the batteries in a well ventilated area only. Do not charge batteries near
fire, flame, or other ignition sources. Batteries being charged may emit highly
explosive hydrogen gas. Failure to properly ventilate the charge gases may result
in serious injury or death.
1. Move the boom lift to a well ventilated area with direct access to a grounded
120 VAC electrical outlet. Make sure the recharge area is not near fire, flame or
other ignition sources.
2. Turn the BATTERY ON/OFF switch to the OFF position.
3. Plug a short, heavy-duty power cord into the battery charger receptacle on the
front of the battery compartment. The recommended power cord should be an
12 AWG multi-strand, grounded cord no longer than 20 feet (6 meters).
NOTE: Using an underrated or lo ng power cord will reduce the output of the
battery charger, resulting in longer charge time.

5. To determine the charge rate at any time during the charge cycle, observe the
DC ammeter (Figure 3-7). The ammeter needle moves to the right at the start of
the charge cycle. As the battery charge rises, the needle moves farther left.
Figure 3-7. Battery Charger
CAUTION
Always remember to unplug the battery charger power cord before moving the
boom lift. Failure to unplug the power cord will cause damage to the equipment.
6. Inspect the charge indicator LEDs near the end of the expected charge cycle. If
all indicator LEDs are off, the battery is fully charged. (The DC ammeter needle
should point to the left.)
NOTE: The yellow 80% CHARGE indicator lights up when the battery voltage is
nearing full charge. At full charge (3-1/2 hours after the 80% CHARGE
indicator lights up), the charger turns off.
If the battery voltage does not reach the 80% CHARGE level in 14 hours,
the charger turns off and the red CHECK BATTERY indicator LED
lights up. This prevents extended charging of a faulty battery.
7. Unplug the power cord from the 120 VAC receptacle and the charger receptacle.
Properly store the power cord for next use.
