onto the operator’s toes. If this safety system is not working correctly, do not operate the unit. Call a maintenance worker right away.

Loading the Unit

1.Before operating the unit, please read and understand all of this section.

2.Be sure that the load weighs no more than the maximum rated for the unit. The maximum rated load is listed on the data plate. Remember that an empty pallet may weigh 40 Ibs (18 kg) or more.

3.The load should always be balanced in the side-to-side direction. Whenever possible, place the load in the center of the pallet, as shown in Fig. 3. If the load is off-center on the pallet, place the heaviest part of the load near the back of the platform - never near the front!

WARNING!

•Don’t try to lift a load that exceeds the maximum rating. If you do not follow these rules, the unit may fail

suddenly. Someone may be hurt, or the unit and load may be damaged.

• The unit is designed so it can lift the rated load if the load center is placed over the center of the platform. (The load center should be 24" or 61 cm from the rear of the platform.) If the load is placed “offcenter,” near the front of the platform, the unit will not be able to lift the rated load safely. It is also important that the load be centered side-to-side. For these reasons, it is very important to be sure the load is centered in the platform area.

4.Sometimes the unit may be used to lift parts which can roll. Stack the parts on the pallet so they cannot roll. Be sure that all parts of the load are secure, and will not move as the unit is operated.

Raising the Platform

1.Before raising the platform, be sure all workers are clear of the unit.
