Fundamentals
This machine is a self-propelled hydraulic lift equipped with a work platform on the scissor mechanism. Vibrations emitted by these machines are not hazardous to an operator in the work platform. The machine can be used to position personnel with their tools and supplies at position above ground level and can be used to reach work areas located above and over machinery or equipment.
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 manual.
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 manual. That means every new operator should perform a pre-operation inspection, function tests, and a workplace inspection before using the machine.

Use the direction arrows on the platform controls to identify the direction the machine will travel.
Machine travel speed is restricted when the platform is raised.
For ERT models, the battery condition will affect machine performance. Machine drive speed and function speed will drop when the battery level indicator is flashing.
Drive speed select
The following drive speeds are only allowed when the machine is stowed. In elevated drive only a restricted creep speed is allowed.
• Speed 1 is the high torque drive which initiates traction control valves. This should be used when driving on any slopes greater than 10% or on rough ground.
•
• Speed 2 is a medium speed suited for driving on flat but unimproved surfaces.
Speed 3 is the fastest speed suitable only when on a smooth flat improved surfaces when conditions are safe.
Driving on a slope
Determine the slope and side slope ratings for the machine and determine the slope grade.
Maximum forward slope rating, stowed position 40%. Maximum side slope rating, stowed position
10%.
Note:
Slope rating is subject to ground conditions and adequate traction.
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 the 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 = 3.6 m
•
• Rise = 0.3 m
0.3 m ÷ 3.6 m = 0.083 × 100 = 8.3%
