TOOL USE AND CARE
1. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger
industrial tool. The tool will perform better and more safely at the task for which it was intended. Do not
modify this tool or use for a purpose for which it was not designed.
2. Securely hold this tool using both hands. Using tools with only one hand can result in loss of control.
3. Maintain tools with care. Keep tools clean, and in good condition for a better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool fittings, alignment periodically and, if
damaged, have them repaired by an authorized technician or replaced. The handles must be kept clean, dry
and free from oil and grease at all times. A properly maintained tool reduces the risk of binding and is easier
to control. Applying excessive force can lead to slips and damage to your work or personal injury.
4. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or
machine before connecting it. A wrench or key that is left attached to a rotating part of the tool increases the
risk of personal injury.
5. Avoid unintentional starts. Be sure that the switch is in neutral or OFF position when not in use and before
connecting it to any power source. Do not carry the tool with fingers near or on the switch.
6. Only use the lubricants supplied with the tool or specified by the manufacturer. Other lubricants may not be
suitable and may damage the tool or even make the tool explode.
7. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.
8. Maintain the label and name plate on the tool. These carry important information. If unreadable or missing,
contact Princess Auto for a replacement.
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient amount of high-grade lubricant for the life of the unit
under normal conditions. Therefore, no further lubrication is required.
WARNING! NEVER use WD-40 to clean or lubricate your tool. WD-40 is a solvent that will break down the
internal grease and cause the tool to seize up.
UNPACKING
1. Carefully remove the parts and accessories from the box.
2. Make sure that all items listed in the parts lists are included.
3. Inspect the parts carefully to make sure the tool was not damaged while shipping.
4. Do not discard the packaging material until you have carefully inspected and satisfactorily operated the tool.
WARNING! If any part is missing, do not operate the tool until the missing parts are replaced. Failure to do so
could result in serious personal injury.
