HYDRAULIC PUMP WARNINGS AND PRECAUTIONS
WARNING: When using the tool, basic safety precautions should always
be followed to reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep the work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools
in damp or wet locations. Don’t expose to rain. Keep the work area
well-lighted. Do not use electrically powered tools in the presence of
flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area.
Do not let them handle machines, tools, or extension cords.
4. Store idle equipment. When not in use, tools must be stored in a dry
location to inhibit rust. Always lock up tools and keep them out of reach of
children.
5. Do not force the tool. It will do the job better and more safely at the rate
for which it was intended. Do not use inappropriate attachments in an
attempt to exceed the tool's capacity.
6. 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. There are certain
applications for which this tool was designed. Do not modify this tool, and
do not use this tool for a purpose for which it was not intended.
7. Dress properly. Do not wear loose clothing or jewelry, as they can be
caught in moving parts. Protective, electrically non-conductive clothes, and
non-skid footwear are recommended when working. Wear restrictive hair
covering to contain long hair.
8. Use eye and ear protection. Always wear ANSI-approved impact safety
goggles. Wear a full face shield if you are producing metal filings or wood
chips. Wear an ANSI-approved dust mask or respirator when working
around metal, wood, and chemical dust and mists.
9. Do not overreach. Keep proper footing and balance at all times. Do not
reach over or across running machines.
10. Maintain tools with care. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing
accessories. Inspect tool cords periodically and, if damaged, have them
repaired by an authorized technician. The handles must be kept clean, dry,
and free from oil and grease at all times.
11. Disconnect power. Unplug the tool when not in use.
12. Remove adjusting keys and wrenches. Check that keys and
adjusting wrenches are removed from the tool or machine work surface
before plugging it in.
13. Avoid unintentional starting. Be sure the switch is in the Off position
when not in use and before plugging in. Do not carry any tool with your
finger on the trigger, whether it is plugged in or not.
14. Stay alert. Watch what you are doing, and use common sense. Do not
operate any tool when you are tired.
15. Check for damaged parts. Before using any tool, any part that
appears damaged should be carefully checked to determine that it will
operate properly and perform its intended function. Check for alignment
and binding of moving parts, any broken parts or mounting fixtures, and
any other condition that may affect proper operation. Any part that is
damaged should be properly repaired or replaced by a qualified technician.
Do not use the tool if any switch does not turn On and Off properly.
16. Guard against electric shock. Prevent body contact with grounded
surfaces such as pipes, radiators, ranges, and refrigerator enclosures.
17. Replacement parts and accessories. When servicing, use only
identical replacement parts. Use of any other parts will void the warranty.
Only use accessories intended for use with this tool.
18. Do not operate the tool if under the influence of alcohol or drugs.
Read warning labels on prescriptions to determine if your judgment or
reflexes are impaired while taking drugs. If there is any doubt, do not
operate the tool.
19. Use the proper size and type of extension cord. If an extension cord
is required, it must be of the proper size and type to supply the correct
current to the tool without heating up. Otherwise, the extension cord could
melt and catch fire or cause electrical damage to the tool. This tool requires
the use of an extension cord of 0 to 12 amps capability (up to 50 feet), with
wire size rated at 16 AWG. Longer extension cords require larger size
wires. If you are using the tool outdoors, use an extension cord rated for
outdoor use. (signified by “WA” on the jacket).
20. Maintenance. For your safety, service and maintenance should be
performed regularly by a qualified technician.
21. If you have a heart pacemaker, the operation of electrical equipment
in close proximity to a heart pacemaker could cause interference or failure
of the pacemaker. Note: The performance of this tool (if powered by line
voltage) may vary depending on variations in local line voltage. Extension
cord usage may also affect tool performance. Warning: The warnings,
cautions, and instructions discussed in this instruction manual cannot
cover all possible conditions and situations that may occur. It must be
understood by the operator that common sense and caution are factors
that cannot be built into this product but must be supplied by the operator.
