3.0 Safety Warnings

1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machi ne and in t his manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This band saw is d esigned a nd 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 bee n obtai ned.

5. Do not use t his band saw for other than its intended use. If used for other purposes, Walter M eier (Manufacturi ng), I nc., disclai ms any real or i mplied warra nty a nd holds itself harmless from any injury that may result from that use.

6. Always wear ANSI approved safety glasses/face shields while using this band saw. Ever y day eyeglasses only have impact resis tant lenses; they are not saf ety glas ses.

7. Before operating this machine, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Nonslip footwear or anti-skid floor strips are recommended.

8. Wear ear protectors ( plugs or muffs) during extended periods of operat io n.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductiv e harm. Some e xamples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement

and other masonry products.

• Arsenic and chromium from chemically

treat ed lumber.

Your risk of e xposure varies, de pending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well- ventilated area a nd work w ith approved safety eq uipment, s uch as face or

dust masks that are specifically desig ned to filter out microscopic particles.

10. Do not operate this machine while tired or under the i nfluence of dr ugs, alc ohol or a ny medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adj usti ng keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the mac hine is i n use. If removed f or maintenance purposes, use extreme c aution and replace the guards immediately after maintenance is complete.

16. Make sure workpiece is securely clamped i n the vise. Never use your hand to hold t he workpiece.

17. Check coolant le vel fr equently. Replace dirty or weak c oolant.

18. Check damaged part s. Befor e furt her us e 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 a ny other conditio ns that may aff ect its operation. A guard or other part that is damaged should be properly repaired or replaced.

7.3 Assemb l y

Refer to Figur e 4.

Band Saw should be

disconnected from electrical power during assembly and setup.

1. Remove bracket s holdi ng saw to pallet.

2. Use proper ly r at ed lift ing equipment (hoist or

forklift ) wit h straps placed be neath cas t iro n portion of saw.

3. Use blocking be neath saw, and install foot

stand (H). Secure with four screws and washers (HP-1/2/3) .

4. Install axle and wheels (F/G). Install cotter

pin (HP-8) through hole in axle, and bend back legs of cotter pin to secure each wheel.

5. Slide work st op r od ( B) into ho le on saw base

and slide workst op (A) onto rod. ( NOTE: Do not insert rod too far so that it hits the vise leadscrew).

Figure 4

6. I nstall handle (E), and place filter scr een (C) over coolant drain hole in pan.

7. Remove stop bo lt ( X, Figure 4) a nd remove shipping bracket (Y ). Retain bracket i n case you must transport the machine in the future. Reinstal l stop bolt .

After removal of shipping bracket (Y), the stop bolt (X) must be reinstalled and proper ly adjusted to prevent damage to t he on/ of f switch.

7.4 Vert ical cutt ing pl at e

These steps are only necessary when using band saw in vert ical position.

1. Disco nnect mac hi ne from pow er source.

2. Raise bow t o vert ical positio n.

3. Remove two screw s and remove seat plat e,

as shown in F ig ure 5.

Figure 5

4. Guide blade t hrough slot in vertical cutting plate (D, Fig ure 5), and tig hten wit h the two screws.

Figure 8

7.5 Co olant syst em

5. Verif y that vert ical c utti ng plate is sq uare to blade, using a machinist’s square on the plate and against the blade (Figure 6).

Figure 6

6. I f adjustme nt is needed, loose n screw s and place shims where required. Tighten screw s .

7. Place a le vel on vertical cutti ng plate ( Figure

7).

Make sure t here is coo lant in

the tank bef or e oper at in g, to prevent da mage to pump.

Use of a water-soluble coolant will increase cutting efficiency and prolong blade life. Do not use black cutting oil as a substitute.

1. Remove coolant return hose (A, Figure 9) from filter cup, and slide tank out of saw base.

2. Fill tank to approximately 80% of capacity. Full capacity is 9 liters ( 2.25 gal).

3. Place tank into base. Place coolant return hose into t he filter cup. Verify t hat opposite end of coolant return hose is connected to the coolant pan.

4. The coolant supply hose (B, Figure 9) should connect to the taps on the blade guide assemblies.

Figure 7

8. Turn stop screw (J, Figure 8) as needed, until cutting plate is level. Tighten hex nut.

9. Close valve o n cylinder ( lever perpe ndicular to cylinder) to secure bow in position.

Reinstall seat plate before using bow in horizont al position.
