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-400P. 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-400P HORIZONTAL BAND RESAW -7-
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.

SECTION 2：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 HP-400P is rewiring for 3-phase operation.
The Model HP-400P has three 25 HP main motor and three 1/4 HP elevation 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.
