Illustration 6	g00567806

The machine must be positioned square to the intended load. Approach the load slowly with the boom in the travel position and get as close to the load as possible.
Engage the parking brake and move the transmission control to the NEUTRAL position.
If necessary, level the frame before you raise the boom or before you engage the load. Do not level the frame when the boom is raised.

Illustration 7 g00722220
If you are operating with stabilizers, lower the stabilizers until the front tires are just clear of the ground and the frame is level.
Show/hide table

Illustration 8 g00722221
Tilt the quick coupler until the forks are level. The machine is equipped with an automatic system for keeping the quick coupler at the selected angle when the boom is raised or lowered.
Show/hide table

Illustration 9 g00569511
Ensure that the forks are spread apart as far as possible. This gives increased stability to the load.
Show/hide table

Illustration 10 g00722222
Raise the boom and extend the boom. The forks must be in line with the pockets of the load.
Use the load chart to assess the intended load. The load chart must indicate that the intended load is within the capacity of the machine. Refer to Operation and Maintenance Manual, "Load Charts".
Show/hide table

Illustration 11 g00722223
Extend and lower the boom. The forks must enter the pockets of the load cleanly. The forks must be fully engaged with the pockets of the load. Take care not to dislodge the load.
Show/hide table

Illustration 12 g00722224
Raise the load carefully. When you are sure that the machine is stable, tilt the quick coupler backward in order to raise the load. If you are not sure that the machine is stable, tilt the quick coupler forward in order to lower the load. Do not proceed. Reposition the machine in order to shorten the reach before you attempt to lift the load again.

If you are operating with stabilizers, lower the stabilizers until the front tires are just clear of the ground.
Show/hide table

Illustration 17 g00722228
Raise the boom and extend the boom until the load is directly over the set down position. Do not exceed the maximum angle of the boom and do not exceed the maximum length of the boom. Use the load chart to determine the maximum angle of the boom and the maximum length of the boom.
Proceed with caution when you approach the maximum angle and/or extension indicated by the load chart. If you are not sure that the machine is stable, retract the boom. Lower the load to the travel position. Move the machine closer to the load placement location. If the machine cannot be moved closer to the load placement location, the load placement location is outside the capacity of the machine. The load cannot be placed at the intended load placement location.
