1. Finish uncrating the saw and inspect for damage. Should any have occurred, contact your local distributor.

2. Remove all bolts attaching machine to shipping base.

3. Leave packing material between vise clamps and saw

head intact until band saw has been lifted to its ﬁ nal position.

4. Clean all rust protected surfaces with kerosene or

diesel oil to remove protective coating. Do not use gasoline, paint thinner, mineral spirits, etc. These may damage painted surfaces.

5. Lubricate all slideways with SAE 10W oil.

7.0 INSTALLATION

For best performance, the band saw should be located on a solid and level foundation. Allow room for servicing and for moving large stock around the band saw when deciding a location for the machine.

1. Using lifting straps that are isolated from the band

saw’s ﬁ nished surfaces, lift machine and place in desired location. See Figure 1 for strap placement.

2. Install four leveling bolts with lock nuts on both sides

of the base as shown in the parts breakdown on page 16, items 2 and 3.

3. Place a level on the table surface and check side-to-

side and front-to-back.

4. Adjust leveling screws until machine is level in both

directions and tighten locking nuts.

8.0 ELECTRICAL CONNECTIONS

All electrical connections must be done by a qualiﬁ ed electrician. All adjustments or repairs must be done with machine disconnected from power source. Failure to comply may cause serious injury.

The EHB-916V Band Saw is rated at 115/230V single phase, and is pre-wired 115 volt from the factory. The EHB-1018V is rated at 230V only, single phase. Conﬁ rm that power available at the saw’s location matches that for which the saw is wired.

To convert the EHB-916V from 115V to 230V, the following items will have to be changed:

Main Motor – follow diagram inside junction box cover. Coolant Pump – Remove chip pan on front of saw,

remove junction box cover on pump, and follow diagram inside junction box cover.

Control Transformer – Open electrical panel on rear of base and change the fuse from 115V to 230V.

Machine must always be correctly grounded.

NOTE: The power cord end will have to be changed to one rated 230V when changing to the higher voltage.

9.0 CONTROLS

11.0 PRIOR TO OPERATION

Refer to Figure 2. Power Indicator Light (A) – lit whenever machine is

running.

If the bulb is out, lamp will not light, but machine may still have power.

Start Button (B) – press to start band saw. Emergency Stop Button (C) – press to immediately stop

all machine functions. Coolant Switch (D) – Turn arrow to “I” to turn on coolant

ﬂ ow. Turn arrow to “O” to stop coolant ﬂ ow. Feed Rate Control (E) – this knob is used to set the

amount of downward force that is applied to the saw blade. The feed rate is proportional to the opening of the valve. When set to zero, the saw head is locked in the raised position. Increasing the valve opening (counterclockwise adjustment) increases the feed rate; decreasing the valve opening (clockwise adjustment) reduces the feed rate.

1. Check that blade tooth direction matches diagram on blade guides.

2. Check to see that blade is properly seated on wheels after applying correct tension (approximately 25,000 lbs.).

3. Set blade holder guides for approximately .003” to .005” clearance between guides and blade.

4. Check for slight clearance between back up rollers and back of blade.

5. Position blade guides as close to workpiece as pos- sible.

6. Select proper speed and feed rate for material being cut.

7. Material to be cut must be securely held in vise.

8. Check to see that coolant level is adequate and turn on coolant pump if material to be cut requires it. Machine should be ﬁ lled with four gallons of the proper coolant mixture. Follow the directions on the product maker’s label and ﬁ ll the coolant tank through the chip tray area.

9. Do not start cut on a sharp edge.

10. Keep machine lubricated. See “Lubrication” section.

Adjustment”.

Fig. 3

Fig. 5

Fig. 4

7. Place the blade in place on the wheels (A) and through the upper blade guard (B) Fig. 3 is shown with the wheel covers removed for clarity.

8. Work the blade (F) all the way up into the blade guide roller bearings (D) with the back of the blade against the back-up bearing (E), as shown in Fig. 4.

NOTE: If roller bearings need adjusting refer to

the section ADJUSTING BLADE GUIDE ROLLER BEARINGS.

9. Put light tension on the blade and work it on both wheels, as shown in Fig. 5.

12.2 ADJUSTING BLADE GUIDE BRACKETS

The blade guides should be set as close to the vise jaw as possible. The right blade guide bracket (A) Fig. 6, is not adjustable and is set at the factory to clear the right hand vise jaw. The left blade guide bracket (B) can be moved to the left or right depending on the position of the left hand vise jaw (C). To move the left blade guide bracket (B), loosen hand knob (D), position blade guide bracket (B) and tighten

hand knob (D).

Note: when operating 916/SA, the right blade guide bracket (A) can be moved as well, especially when cutting in 90° to make sure the bracket be moved as close to the vise jaw as possible.

MAKE SURE THAT THE BACK OF THE BLADE

IS AGAINST THE WHEEL FLANGES OF BOTH WHEELS. THIS IS VERY IMPORTANT.

10. When you are sure the back of the blade is against the wheel ﬂ anges of both wheels and properly insert- ed into the guides, ﬁ nish putting tension on the blade.

12.3 ADJUSTING BLADE GUIDE ROLLER

BEARINGS

12.4 CHANGING BLADE SPEED

The back of the blade (A) Fig. 7, should ride against the back-up support bearing (B) which is positioned at an angle so as to provide greater bearing support, eliminating

bearing wear and extending blade life. The saw blade (A) should also ride between the two roller

bearings (C) and (D) Fig. 7. The rear bearing (C) on the left hand blade guide can

be easily adjusted to suit blade thickness by loosening nut (E). The bearing (C) is on an eccentric shaft which enables it to be adjusted for blade thickness in the same manner with the exception that the adjustable roller bearing is in the forward position.

Part (F) shown Fig. 8 is a tungsten carbide block, after completing the adjustments shown in Fig. 7, tighten the Part (F) onto the surface of the saw blade.

Only adjust speed with power on and blade turning.

1. Raise cutting head approximately six inches above work piece and turn feed rate knob to zero.

12.6 BOW WEIGHT ADJUSTMENT

Bow weight is one of the most important adjustments of the saw. If the bow weight is not set properly, one can expect poor performance, crooked cuts, tooth stripping, stalling, and the blade popping off the blade wheels. The hydraulic feed rate unit will not compensate for improper bow weight. Bow weight has been set at the factory and should not need any adjustment. If adjustment becomes necessary:

1. Disconnect machine from power source.

2. Turn feed rate control (E, Figure 2)

counterclockwise until it stops.

3. Place one end of a ﬁ sh-type scale under the blade

tension handle and lift the saw with the other end. The scale should indicate approximately 18-20 lbs. for the HBS-916W. For the HBS-1018W, it should indicate 22-24 lbs.

4. Adjust tension to approximately 18-20 lbs. (or 22-24

lbs.) by turning the adjustable C-bolt found at the end of the coil spring on the rear of the band saw.

5. Connect the machine to the power source.

Fig. 11

12.8 SETTING UP THE MACHINE FOR OPERATION

1. Select the proper speed and blade for the type of

material you are cutting.

2. Make sure blade tension is adjusted properly.

3. Lift the saw frame up and close the feed rate lever.

4. Place the stock between the vise jaws, set the stock

for the desired width of cut and tighten the vise.

5. Make sure the left blade guide bracket (A) is adjusted

as close as possible to the left vise jaw (B) Fig. 12.

6. Turn the machine on and if your machine is equipped

with a coolant system, adjust coolant ﬂ ow by turning lever (D) Fig. 2.

7. Turn the feed rate control (E) Fig 2, counterclock

wise until the saw blade begins to lower the desired rate of speed.

8. Proceed to cut throughout the workpiece, as shown in

Fig. 12. Shut the machine off upon completion of cut.

12.7 ADJUSTING STOCK ADVANCE STOP

The Stock Advance Stop is used mainly when more than one piece is to be cut to the same length. Simply position the stop block (A) Fig.11, the desired distance away from the blade.

The stop may be repositioned by loosening screw (B) and moving the rod (C) accordingly. To move the stop block (A) out of the way simply push it to the down position.
