SAFETY RULES

Do not use the platform controls to free a platform
that is caught, snagged or otherwise prevented
from normal motion by an adjacent structure. All
personnel must be removed from the platform
before attempting to free the platform using the
ground controls.

Pre-operation Inspection

Fundamentals

It is the responsibility of the operator to perform a
pre-operation inspection and routine maintenance.

The pre-operation inspection is a visual inspection
performed by the operator prior to each work shift.

Do Not Operate Unless:

You learn and practice the principles of safe

machine operation contained in this operator's
manual.

1 Avoid hazardous situations.

2 Always perform a pre-operation

inspection.

Know and understand the pre-operation

inspection before going on to the next
section.

3 Always perform function tests prior to use.
4 Inspect the workplace.
5 Only use the machine as it was intended.

The inspection is designed to discover if anything
is apparently wrong with a machine before the
operator performs the function tests.

The pre-operation inspection also serves to
determine if routine maintenance procedures are
required. Only routine maintenance items specified
in this manual may be performed by the operator.

Refer to the list on the next page and check each
of the items.

If damage or any unauthorized variation from
factory delivered condition is discovered, the
machine must be tagged and removed from
service.

Repairs to the machine may only be made by a
qualified service technician, according to the
manufacturer's specifications. After repairs are
completed, the operator must perform a
pre-operation inspection again before going on to
the function tests.

Scheduled maintenance inspections shall be
performed by qualified service technicians,
according to the manufacturer's specifications and
the requirements listed in the responsibilities
manual.

Maintenance

Check the Hydraulic Oil Level

Maintaining the hydraulic oil at the proper level is
essential to safe machine operation. Improper
hydraulic oil levels can damage hydraulic
components. Daily checks allow the inspector to

Only routine maintenance items specified in this

manual shall be performed by the operator.

Scheduled maintenance inspections shall be

completed by qualified service technicians,
according to the manufacturer's specifications
and the requirements specified in the
responsibilities manual.

identify changes in oil level that might indicate the
presence of hydraulic system problems.

Perform this procedure with the
platform in the stowed position.

1 Visually inspect the hydraulic oil level through

the indicator at the back of the machine.

Result: The hydraulic oil level should be visible.

2 Add oil if necessary. Do not overfill.

Maintenance Symbols Legend

The following symbols have been
used in this manual to help
communicate the intent of the
instructions. When one or more of
the symbols appear at the
beginning of a maintenance
procedure, it conveys the meaning
below.

MAINTENANCE

Check the Batteries

Proper battery condition is essential to good
performance and operational safety. Improper fluid
levels or damaged cables and connections can
result in component damage and hazardous
conditions.

This procedure does not need to
be performed on machines with
sealed or maintenance - free
batteries.

Electrocution hazard. Contact with
hot or live circuits could result in
death or serious injury. Remove all
rings, watches and other jewelry.

Bodily injury hazard. Batteries
contain acid. Avoid spilling or
contacting battery acid. Neutralize
battery acid spills with baking soda
and water.

7 Remove the battery vent caps.
8 Check the battery acid level. If needed,

replenish with distilled water to the bottom of the

battery fill tube. Do not overfill.
9 Install the vent caps.
10 Raise the platform and lower the cover.

Scheduled Maintenance

Maintenance performed quarterly, annually and
every two years must be completed by a person
trained and qualified to perform maintenance on this
machine according to the procedures found in the
service manual for this machine.

Machines that have been out of service for more
than three months must receive the quarterly
inspection before they are put back into service.

Perform this test after fully

charging the batteries.
1 Put on protective clothing and eye wear.
2 Raise the platform approximately 1.5 m.
3 Open the battery cover. Rest the cover against

the chassis.

4 Lower the platform until the mast just contacts

the battery cover.

Crushing hazard. Keep hands clear

of the battery cover when lowering

the platform.
5 Turn the key switch to the off position.
6 Be sure that the battery cable connections are

tight and free of corrosion.

Operator's Manual

Operating Instructions

Fundamentals

The Operating Instructions section provides
instructions for each aspect of machine operation.
It is the operator's responsibility to follow all the
safety rules and instructions in the operator's,
safety and responsibilities manuals.

Using the machine for anything other than lifting
personnel, along with their tools and materials, to
an aerial work site is unsafe and dangerous.

Only trained and authorized personnel should be
permitted to operate a machine. If more than one
operator is expected to use a machine at different
times in the same work shift, they must all be
qualified operators and are all expected to follow all
safety rules and instructions in the operator's,
safety and responsibilities manuals. That means
every new operator should perform a pre-operation
inspection, function tests, and a workplace
inspection before using the machine.

OPERATING INSTRUCTIONS

To Reduce Drive Speed

The drive controls can operate in two different drive
speed modes. When the drive speed button light is
on, slow drive speed mode is active. When the
button light is off, fast drive speed mode is active.

Press the drive speed button to select
the desired drive speed.

Driving on a slope

Determine the slope and side slope ratings for the
machine and determine the slope grade.

Maximum slope rating, stowed
position: 30% (17°)

Maximum side slope rating,
stowed position: 30% (17°)

Note: Slope rating is subject to ground conditions
and adequate traction.

Press the drive speed button to the fast drive
speed mode.

To determine the slope grade:

Measure the slope with a digital inclinometer OR
use the following procedure.

You will need:

carpenter’s level
straight piece of wood, at least 1 m long

tape measure
Lay the piece of wood on the slope.
At downhill end, lay the level on the top edge of the

piece of wood and lift the end until the piece of
wood is level.

While holding the piece of wood level, measure the
distance from the bottom of the piece of wood to
the ground.

Divide the tape measure distance (rise) by the
length of the piece of wood (run) and multiply by

100.

Example:

run

rise

Run = 3.6 m

Rise = 0.3 m

0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3%

If the slope exceeds the maximum slope or side
slope rating, the machine must be winched or
transported up or down the slope. See Transport
and Lifting section.
