10. Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Non-slip footwear is recommended. Wear protective hair
covering to contain long hair.
11. Always use safety glasses. Also use face or dust mask if cutting operation is dusty. Everyday
eyeglasses only have impact resistant lenses, they are not safety glasses.
12. Secure work. Use clamps or a vise to hold work when practical. It is safer than using your hand and
frees both hands to operate tool.
13. Do not overreach. Keep proper footing and balance at all times.
14. Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
15. Use recommended accessories. Consult the instruction manual for recommended accessories. The use
of improper accessories may cause risk of injury.
16. Reduce the risk of unintentional starting. On machines with magnetic contact starting switches there
is a risk of starting if the machine is bumped or jarred. Always disconnect from power source before
adjusting or servicing. Make sure switch is in off position before reconnecting.
17. Many woodworking tools can “kickback” the workpiece toward the operator if not handled properly.
Know what conditions can create “kickback” and know how to avoid them. Read the manual
accompanying the machine thoroughly.
18. Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check
for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other
conditions that may affect its operation. A guard or other part that is damaged should be properly
repaired or replaced.
19. Never leave tool running unattended. Turn power off. Do not leave tool until it comes to a complete
stop.
20. Never operate a machine when tired, or under the influence of drugs or alcohol. Full mental alertness
is required at all times when running a machine.
21. Never allow unsupervised or untrained personnel to operate the machine. Make sure any instructions
HP-11P 7
you give in regards to the operation of the machine are approved, correct, safe, and clearly
understood.
WARNING：
Additional Safety Instructions for Bandsaw
1. Do not operate with dull or badly worn blades. Dull blades require more demand on the motor and are
less likely to cut precisely. Inspect blades before each use.
2. Never position fingers or thumbs in line with the cut. Serious personal injury could occur.
3. Do not operate this bandsaw without wheel guards, pulley guards, and blade guards in place.
4. When replacing blades, make sure the teeth face toward the front of the saw.
5. Cuts should always be fully supported against the side of the conveyor table and by the pressure rollers.
6. Do not back workpiece away from the blade while the saw is running. If you need to back the work out,
stop the bandsaw and wait for the blade to stop. Do not twist or put excessive stress on blade while
backing work away.
7. Blade should be running at full speed before beginning a cut.
8. Always feed stock evenly and smoothly. Do not change conveyor speeds during a cut.
9. This machine is not designed to cut metal or other material except wood.
10. Do not manually stop or slow blade after turning the saw off. Allow it to come to a complete stop
before you leave it unattended.
11. All inspections, adjustments, and maintenance must be done with the power off and the circuit breaker
shut off. Wait for all moving parts to come to a complete stop.
12. Habits – good and bad – are hard to break. Develop good habits in your shop and safety will become
second- nature to you.
13. If at any time you are experiencing difficulties performing the intended operation, stop using the
bandsaw. Then contact our service department or ask a qualified expert how the operation should be
performed.
14. Make sure blade is properly tensioned before operating machine.
15. Keep loose clothing and long hair away from moving conveyors!
WARNING：
Like all power tools, there is danger associated with the Model HP-11P. Accidents are frequently caused
by lack of familiarity or failure to pay attention. Use this tool with respect and caution to lessen the
possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal
injury may occur.
CAUTION：
No list of safety guidelines can be complete. Every shop environment is different. Always consider safety
first, as it applies to your individual working conditions. Use this and other machinery with caution and
respect. Failure to do so could result in serious personal injury, damage to equipment, or poor work
results.
HP-11P 8
WARNING：
Additional Safety Instructions for Hydraulics
1. Be familiar with the hazards of hydraulic injection injuries. Leaking hydraulic fluid may have enough
pressure to penetrate skin. Never use your hands to check for suspected hydraulic leaks.
Hydraulic fluid that is injected into skin is a medical emergency that may cause infection, disability,
amputation or death.
The average injection injury may be a small wound that has barely broken the skin. Do not be fooled
by this type of injury. Immediately get to an emergency medical facility!
Minimizing the time between the injury and when the injected material is removed is critical to
minimizing the seriousness of the injury.
2. Use a piece of cardboard to check for suspected hydraulic leaks. Pressurized hydraulic fluid may cause
injection injuries and can be extremely hot. Never use your hands to check for suspected hydraulic
leaks.
3. Protect your eyes around hydraulic systems. Safety glasses may not always protect your eyes from hot,
pressurized fluid. The best way to protect yourself is to stay away from leaks until you can depressurize
the system.
4. Stop the machine if you notice a hydraulic leak. Allowing the machine to continue running with a leak
may increase the hazard of the situation.
5. Depressurize the hydraulic system before attempting to adjust any hydraulic lines or fittings. Stop the
resaw, open the conveyor speed valves, and make sure the pressure gauge reads 0 psi.
6. Depressurize the hydraulic system before attempting any maintenance or service. Stop the resaw, open
the conveyor speed valves, and make sure the pressure gauge reads 0 psi.
7. Regularly inspect and perform the proper maintenance on the hydraulic system. A well-maintained
hydraulic system will have much few problems and hazards than a neglected system.
8. Make sure any hydraulic system maintenance is performed in a clean and dust-free work area. Remove
any sawdust, grime or water from hydraulic system openings or components before maintenance.
Always use lint-free rags when wiping components.
9. Only use high pressure hydraulic hose and steel hydraulic fittings when replacing components in the
hydraulic system. Do not use brass or aluminum.
WARNING：
Additional Safety Instructions for Machine Lifting
1. Use enough capacity of forklift to raise or move the machine.
2. Pay special attention to the machine balance while in lifting.
3. Have another person to help guiding the way when lifting the machine.
4. Make sure the fork of the forklift protrudes over the machine bottom.
5. Do not raise the machine too high as this will cause poor stability.
6. Forklift should be driven by experienced personnel only.

SECTION 3：CIRCUIT REQUIREMENTS
-------------------------------------------------------------------------------------
WARNING：
Serious personal injury could occur if you connect your machine to the power source before you have
completed the setup process. Do not connect the machine to the power source until instructed to do so.
The Model is wirHG for 3-phase operation.
The Model has 20 HP main motor.
Circuit Breaker Requirements
Install your bandsaw on a dedicated circuit to reduce the possibility of overloading the circuit and tripping
the circuit breaker. However, if an unusual load does not exist, and the circuit breaker still trips, have the
circuit inspected by a qualified electrician. Never use a larger circuit breaker than stated below, or you
will increase the risk of fire.
Connection Type
Because of the high amperage draw from this machine, we recommend that you hardwire it directly to
your circuit breaker and install a locking shut-off lever near the machine as a way to quickly disconnect
the power.
Your factory Circuit Capacity
Always check to see if the wires in your circuit are capable of handling the amperage draw from your
machine, as well as any other machines that could be operating on the same circuit. If you are unsure,
consult a qualified electrician.
If the circuit breaker trips or the fuse blows regularly, your machine may be operating on a circuit that is
close to its amperage draw capacity. However, if an unusual amperage draw does not exist and a power
failure still occurs, refer to the troubleshooting section in this manual or contact a qualified electrician or
our service department.
CAUTION：
Be sure that your particular electrical configuration complies with local and state codes. The best way to
ensure compliance is to check with your local municipality or a licensed electrician.
