1.0 IMPORTANT SAFETY

INSTRUCTIONS

WARNING – To reduce risk of injury:

1. Read and understand the entire owner's

manual before attempting assembly or

operation.

2. Read and understand the warnings posted on

the machine and in this manual. Failure to

comply with all of these warnings may cause

serious injury.

3. Replace warning labels if they become

obscured or removed.

4. This band saw is designed and intended for use

by properly trained and experienced personnel

only. If you are not familiar with the proper and

safe operation of a band saw, do not use until

proper training and knowledge have been

obtained.

5. Do not use this band saw for other than its

intended use. If used for other purposes, JET

disclaims any real or implied warranty and holds

itself harmless from any injury that may result

from that use.

6. Always wear leather gloves when handling saw

blades. The operator shall not wear gloves

when operating the machine.

7. Machinery should be anchored to the floor if

there is any risk of sliding or tipping during

operation.

8. Secure work. Use clamps or a vise to hold work,

when practical. It is safer than using your hands

and it frees both hands to operate the machine.

9. All doors shall be closed, all panels replaced,

and other safety guards in place prior to the

machine being started or operated.

10. Be sure that the blade is not in contact with the

workpiece when the motor is started. The motor

shall be started and you should allow the saw to

come up to full speed before bringing the saw

blade into contact with the workpiece.

11. Keep hands away from the blade area.

12. Remove any cut off piece carefully while

keeping your hands free of the blade area.

13. Bring adjustable saw guides and guards as

close as possible to the workpiece.

14. Always wear protective eye wear when

operating, servicing, or adjusting machinery.

Eyewear shall be impact resistant, protective

safety glasses with side shields complying with

ANSI Z87.1 specifications. Use of eye wear

which does not comply with ANSI Z87.1

specifications could result in severe injury from

breakage of eye protection.

15. Wear proper apparel. No loose clothing or

jewelry which can get caught in moving parts.

Confine long hair.

16. Anti-skid floor strips, nonslip footwear and

safety shoes are recommended.

17. Wear hearing protection (plugs or muffs) if

sound reaches unsafe levels.

18. The workpiece, or part being sawn, must be

securely clamped before the saw blade enters

the workpiece.

19. Remove cut off pieces carefully, keeping hands

away from saw blade.

20. Saw must be stopped and electrical supply cut

off or machine unplugged before reaching into

cutting area, before any blade replacement or

adjustment of blade support mechanism is

done, or before any attempt is made to change

the drive belts, or before any periodic service or

maintenance is performed on the saw.

21. Avoid contact with coolant, especially guarding

your eyes.

22. Make certain the switch is in the OFF position

before connecting the machine to the power

supply.

23. This saw must be grounded in accordance with

the National Electrical Code and local codes

and ordinances. This work should be done by a

qualified electrician. The saw must be grounded

to protect the user from electrical shock.

Caution: For circuits which are far away from

the electrical service box, the wire size must be

increased in order to deliver ample voltage to

the motor. To minimize power losses and to

prevent motor overheating and burnout, the use

of wire sizes for branch circuits or electrical

extension cords according to sect. 6.3, Table 2,

is recommended.

24. Remove loose items and unnecessary

workpieces from area before starting machine.

25. Remove adjusting keys and wrenches. Form a

habit of checking to see that keys and adjusting

wrenches are removed from the machine

before turning it on.

26. Keep safety guards in place at all times when

the machine is in use. If removed for

maintenance purposes, use extreme caution

and replace the guards immediately after

completion of maintenance.

27. Check damaged parts. Before further use of the

machine, 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.

28. Maintain all machine tools with care. Follow all

maintenance instructions for lubricating and the

changing of accessories.

29. No attempt shall be made to modify or have

makeshift repairs done to the machine. This not

only voids the warranty but also renders the

machine unsafe.

30. Keep work area clean. Cluttered areas invite

accidents. Keep the floor around the machine

clean and free of scrap material, oil and grease.

31. Keep visitors a safe distance from the work

area. Keep children away.

32. Make your workshop child proof with padlocks,

master switches or by removing starter keys.

33. Give your work undivided attention. Looking

around, carrying on a conversation and “horse-

play” are careless acts that can result in serious

injury.

34. Maintain a balanced stance at all times so that

you do not fall into the blade or other moving

parts. Do not overreach or use excessive force

to perform any machine operation.

35. Use the right tool at the correct speed and feed

rate. Do not force a tool or attachment to do a

job for which it was not designed. The right tool

will do the job better and more safely.

36. Use only recommended accessories; improper

accessories may be hazardous.

37. Keep saw blades sharp and clean for the best

and safest performance.

38. Turn off the machine before cleaning. Use a

brush or vacuum to remove chips or debris —

do not use bare hands. Never brush away chips

while machine is in operation.

39. Do not stand on the machine. Serious injury

could occur if the machine tips over.

40. Never leave the machine running unattended.

Turn off power and do not leave the machine

until it comes to a complete stop.

41. Avoid dangerous working environments. Do not

use stationary machine tools in wet or damp

locations. Keep work areas clean and well lit.
