7/32” hex (Allen) wrench 6mm hex (Allen) wrench 12mm open-end wrench Square Hoist or forklift, with straps

Remove all crati ng and plastic from around the machine. Remov e any screws or straps hol ding the band saw to the shippi ng pallet.

Exercise care when

removing the machine from the shipping pallet.

Use a hoist or f orklift with straps to rem ove the machine fr om the pallet. The straps used shoul d have a minimum 1,000 lb. lifting capacity. Do NOT place forks or straps directly beneath the table or against handles or levers - place the straps under the top portion of the frame, as shown in Figure 3.

Move the band saw to its permanent location, which should be dry and well lit, with enough space on all sides to handle long stock or perform routine maintenance on the machine. Make sure the fl oor is able to support t he weight of the machi ne. If desired, the band saw can be secured to the floor using lag screws (not provided) t hr ough the four holes in the base.

Exposed metal surfaces, such as the table surface and blade guides, have been given a protective coating at the factory. This coating should be rem oved wit h a soft c loth moistened with solvent . Do not get solvents near pl astic or rubber parts; and do not use an abra siv e pad as it may scratch the exposed surfaces.

Assembly

Rear Rail

Refer to Figures 4 and 5.

1. Install the rear rail to the rear edge of the table, using three 5/16-18 x 3/4 hex cap screws (AA), three 5/16 lock washers (BB), and three 5/16 f lat washers (CC) as shown. Hand tighten only .

Figure 3

Figure 4

2. The exact distance from rear rail to table top is not important , but the rear rail should be made parallel to the table top. Place a measuring device, such as a combination square (Figure 5) at front and back of the table as shown.

Figure 5

The measurement should be the same at both ends of the rear rail. Adjust as needed.

3. Tighten the three screws with a 12mm wrench.

Front Rail and Guide Tube

Refer to Figure 6.

4. Install the front rail t o the front edge of the table, using two 5/16-18 x 3/4 hex cap screws (AA), two 5/16 lock washers (BB), and two 5/16 f lat w ashers (CC), through t he slotted holes in the rail. Place the screws approximately center of the slots; this can be adjusted later as needed. Tighten the two screws with a 12mm wrench.

5. Install the guide tube to the bottom holes in the front rail, using five 5/16-18 x 3/4 hex

cap screws (AA), five 5/16 lock washers (BB), and five 5/16 flat w ashers (CC) . Hand

tighten only. Pull the guide tube away from the table as far as it will go, then tighten all five screws in the guide tube with a 12mm wrench. Do not overtighten.

Figure 6

Figure 7

Fence Assembly

Refer to Figures 7 and 8.

Place the fence body onto the guide tube (as shown in Fi gure 8). Rai se the fence l ev er all the way up to install or remove the fence from the guide tube. Midway lever position allows the fence to slide along the gui de tube. Lowest lever position locks the fence in place.

Resaw Fence

Refer to Figures 8 and 9.

Loosen the lock bar using the knobs, until the lock bar protrudes enough to sl ide t he al uminum resaw fence on from one end, as shown in Figure 8. Re-ti ghten the knobs.

NOTE: The aluminum resaw fence can be installed in one of two positions; vertically (resaw position), as shown in Figure 8; or horizontally as shown in Figure 9. Horizontal position is useful for smaller workpieces. (The zero setting of the cursor cannot be used with the horizontal fence position.)

Figure 8 (resaw f enc e vert ic al pos ition)

Figure 9 (horizontal fence posit ion)

Fence to Table Clearance

1. Check the cl earance between the table and the bottom of the fence (Figure 10). The fence should not rub against the table surface but be slightly above it. This gap should be the sam e at the front of the tabl e as it is at the back.

2. If the clearance is not the same, use a combination of the following two adjustments:

• With a 7/32” hex wrench, rotate the two

nylon adjustm ent screws (A, Figure 16) t he same amount to raise or lower the fence body from the guide tube. Clockwise rai ses the fence body, count er c lockwise lowers.

• And/or....A djust the back end of the fence

by loosening one hex nut and tight ening the other (A, Figure 11) in order to raise or lower the sliding pad (B, Figure 11) as needed. When the fence-to-table gap is equal, make sure both hex nuts are tightened against the fence body.

Setting Cursor (Zero) Position

Figure 10

Figure 11

Refer to Figure 12.

The fence must be set so that the cursor reads zero at the line of the blade. The resaw fence must be installed on the f ence body in vertical position, and the blade must be installed and fully tensioned.

1. Slide the fence flush against the flat of the blade, as shown. (Do not force the fence into the blade so that t he blade bends.)

2. If the cursor is not at zero, loosen the t wo screws and slide it as needed. Then retighten the screws.

Setting Table Parallel to Blade

Refer to Figures 13 and 14.

The table has been al i gned by t he m anuf act urer so that the miter slot is parallel to t he flat of the blade; it should not require adjustment. However, i n the future y ou may wish to conf irm this setting is still accurate. A wide blade is recommended for the procedure.

1. Disconnect band saw f r om power source.

Figure 12

2. The blade should be fully tensioned and properly t r acked (see pages 17 and 18).

3. Place a long straightedge flush against the blade making sure it cont acts both front and back of the bl ade. (Do not deflect the blade by pushing into it. ) See Figur e 13.

Figure 13

4. Use a gauge to carefully measure the distance from miter slot to straight edge. Take measurem ents at both front and back of table – these should be the same.

5. If t he miter slot is not parallel to t he blade, loosen the four hex cap screws that secure the table to the trunnion (Figure 14 shows three of them), and shift the table as needed until the miter slot is parallel to the blade.

6. Tighten the four hex cap screws.

Setting Fence Parallel to Blade

Refer to Figures 15 and 16.

The fence should be parallel to the flat of the blade for accurate cutting. Since the miter slot has been set parallel to the blade from the manufacturer (and confirmed by the user, as described above), you can use the table miter slot to set the fence par allelism.

1. Remove the alumi num resaw fence and the mounting bar f rom the f ence body, and sli de the fence body t o the edge of the mi ter slot, as shown in Figure 15. The fence should align with the miter slot along the entire length of the f enc e.

Figure 14

2. If adjustm ent is needed, use one of the back adjustment sc rew s (B, Fi gure 16) t o tur n the

fence in line wit h the miter slot.

The fence must also be parallel to the blade vertically. Refer to Figure 17.

3. Make sure t he tabl e ha s been set 90° t o the blade (see “90° Table Stop”).

4. Mount the resaw fence, and slide the fence up against the blade; do not push into the blade. Turn either of the nylon adjustment screws until fence is parallel to blade along the vertical length of fence.

Fence Locking Tightness

The tightness of the fence against the guide tube can be adjusted by rotating the two back screws (B, Figure 16). Rotate the two screws equally (clockwise to tighten) with a 5mm hex wrench.

Because these screws are also used to align the fence to t he blade, aft er adjusting f ence locking tightness, you should double check fence-toblade relationship, as explained under “Setting Fence Parallel to Blade.”

Dust Collection

The use of a du st collection system is strongly recommended for this band saw. It will help keep the shop clean, as well as reduce pot enti al health hazards caused by inhalation of wood dust. The collector should have a capacity sufficient for this size machine – 400 CFM is recommended. Walter Meier has a line of dust collection system s available; see your dealer or visit our website li sted on the back cover.

Connect the hoses of your dust collection system to the 4” dust ports at the rear of the band saw. Secure ti ghtly with hose clamps (not provided). S ee Figure 18.

Figure 18

Electrical Connections

Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

Single Phase Connections

The single phase B and Saw is fact ory wired for 230 volt s. It is not supplied with a plug. Y ou may either install a UL/CSA-listed plug suitable for 230 volt operati on, or “hard-wire” the B and Saw directly to a service panel.

It is recommended that the single phase Band Saw be connected to a grounded and dedi c ated, minimum 50 amp circuit with a 50 amp circuit breaker or time delay fuse. Local codes take

precedence o ver recommendations.

Three Phase Connections

The three phase Band Sa w is fact ory wired for 230 volt s. It is not supplied with a plug. Y ou may either install a UL/CSA-listed plug suitable for 230 volt operati on, or “hard-wire” the B and Saw directly to a service panel.

The three phase Band Sa w m ay be c onverted t o 460V operation. The current contactor m ust be replaced with t he 460V magnetic contac tor (part no. PM2000-293C, purchased separately). In addition, re-connect the motor leads according to the diagrams inside the motor junction box. (Similar di agrams may be found at t he back of this manual.)

It is recommended that the three phase Band Saw be connected to a grounded and dedi c ated, minimum 30 amp circuit with a 30 amp circuit breaker or time delay fuse. Local codes take

precedence o ver recommendations.

If the single phase or t hree phase Band Saw is to be “hard- wired” t o a serv i ce panel , m ake sure a disconnect i s availabl e for the operator . During hard-wiring of t he machine, make sure t he f uses have been rem oved or the breakers hav e been tripped i n the circuit to which the Band Sa w will be connected. Place a warning placard on the fuse holder or circuit break er to prevent it being turned on while t he machine is being wired.

Grounding Instructions

This machi ne must be grounded. In the ev ent of a malfuncti on or breakdown, grounding prov ides a path of l east resistance for elect ric current to reduce the ri sk of el ectri c shock .

Improper connection of the equipmentgrounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes, is the equipmentgrounding conduct or .

If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool i s properly gr ounded. Repai r or replace a damaged or worn cord im m ediately.

Make sure the voltage of your power supply matches the specif ications on the m otor pl ate of the Band Saw.

Extens ion Cords

The use of extension cor ds i s di scouraged; try to position t he machine within reach of the power source. If an extension cord becomes necessary, m ake sure the cord rati ng is suitable for the am perage listed on t he machine’s m otor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

2. For right tilt (as viewed from front or operator’s side of the saw), rotate the handwheel (B) count erclockwise to ti lt table up to 45°.

3. For left tilt (as viewed from front or operator’s side of the saw), loosen the l ock lever (A) and rotate the handwheel clockwise a turn or two to release pre ssure on the 90° stop bolt (C). Rot ate the circular plate (D) out of the way. Then rotate the handwheel cloc k wise to tilt the table to 15°.

The now-exposed hole in the band saw body allows the stop bolt to descend through it, to keep intact the setting of the 90° stop.

4. Tighten the lock lever (A, Figure 20) to secure the setting.

NOTE: The circular plate (D) can be tight ened or loosened as desired by using a 5/ 32” (4mm ) hex wrench on the screw.

Also, the lever (A, Figure 20) can be pivoted to a more conveni ent positi on. Simply lift str aight out on the lever and rotate it on the pin, then release the lever making sure i t seats itself on the pin.

90° Table Stop

Refer to Figures 20 t hr ough 22.

The 90° positiv e stop ensures that the tabl e will always be perpendicular to the blade after the table is returned to horizontal position. Check and adjust this 90° stop as follows:

1. Disconnect machine from power source.

2. Make sure blade is under f ull tension.

Figure 21

3. Loosen lever (A, Figure 20) and tilt table with the handwheel (B), until the stop bolt (C) rests on the circular plate (D).

4. Make sure the table insert is level with surface of table by rotating one or more of its set screws with a 5/164” (2mm) hex wrench. Then place a square on the table and against the bl ade to check that the table is 90° to the blade. See Figure 22. NOTE: Do not push square into blade.

5. If table and blade are not square, use a 9/16” (14mm) wrench t o loosen the lock nut (E) then rotate the stop bolt. Turn the stop bolt as needed until there i s no longer li ght showing between the square and the blade.

6. Tight en lock nut (E) to secure the table st op in position.

7. Tighten the lever (B).

8. Check that the scale pointer (F, Figure 20) is at zero. If nec essary, loosen the scre w on the pointer and shift the pointer to zero. Then re-tight en the screw.

Installing/Changing Blades

Always wear gloves when

handling blades. New blades are usually packaged in a coiled position; to prevent injury uncoil them slowly and carefully, while wearing work gloves and safety glasses.

The PM1800 Band Sa w is designed f or blades from 1/16” to 1-1/2” wide. The Band Saw is provided with a blade of the following specific ations: 0.03” thick, 3/4” wide, 4 TPI.

Refer to Figures 23 and 24.

1. Disconnect machine from power source.

2. Remove the table insert (A, Figure 23) .

3. Pull out table pin (B) at the end of the slot.

4. Adjust upper and lower blade guides away from the blade.

5. Move the quick tension lever to “Full Release (Blade Change)” posi tion.

6. Open upper and lower door s by rotati ng the door catches. Open the lower blade guard and slide out the i nsert bloc k (Figur e 24).
