The depth of cut can be set from 1 mm to 3 mm. Final thickness stop
With the thickness stop (40) standard planing thicknesses of 1/4″ (6 mm) to 1 3/4″ (44 mm) can be preset.
Using this feature, work pieces are planed to a uniform thickness without the need for constant measuring.

Initial Operation

6.1 Machine Installation
To keep the machine from “wandering” caused by vibrations or to prevent tipping over, the machine must be bolted to a work bench, work stand or similar firm support.
Note:
When installing the machine stationary, keep in mind that there must be sufficient space in front and behind the machine to work long work pieces.

1. Drill holes into supporting surface, where necessary.
2. Put bolts (41) through from the top und secure from below with nuts.

When the machine is to be used mobile:

1. Bolt machine to the work stand (42) (see “Available Accessories”).

Alternative installation:

1. Fasten thicknessing machine to a sheet of 3/4 ” (19 mm) plywood. This sheet should project on each side of the machine base approx. 4 inch (100 mm). Make sure that the fixing screws do not jut out on the underside of the plywood sheet.
2. At the job site, clamp the plywood sheet with G-cramps to a work bench, work stand or similar support.

6.2 Aligning the Infeed and Outfeed Tables
To achieve an optimal planing result, all bearing surface must be level with each other.
Note:
Before starting work, always check to see that the bearing surfaces of the centre table, infeed table and outfeed table are level with each other.
**** Cutting hazard when touching the rotating cutterblock!
Accidental starting of the machine may cause serious injury.
Always unplug before making any adjustments to the machine!

1. Fold down both infeed (43) and outfeed table (45).
2. Put a straight board (46), try square, straight edge or similar across the infeed and outfeed table. If readjustment is necessary:
3. Fold both infeed and outfeed table up.
4. Loosen lock nut (47) on both stop screws (48).
5. Adust both stop screws (48), until the infeed table (or outfeed table) is on a level with the centre table (44) of the thicknessing machine.
6. Fold down the infeed table (or outfeed table) and recheck, if the bearing surfaces are now on a level with each other.
7. When infeed and outfeed table are properly aligned, secure all stop screws (48) with the lock nuts (47).

6.3 Dust Collector

**** Danger!
Some types of wood dust (e.g. beech, oak, ash) can cause cancer when inhaled. To minimize the adverse effect of wood dust, you are stronlgy advised to connect a suitable dust collector to the machine when working indoors.
The dust collector must comply with the following:
– fitting the diameter of the dust extraction connector:
— 21/2″ (64 mm), or
– 4″ (102 mm);
– air flow volume ≥ 460 m³/n;
– vacuum at the dust extraction connector ≥ 530 Pa;
– air speed at dust extraction connector ≥ 20 m/s.
Follow the operating instructions supplied with the dust collector as well!
Operation without a dust collector is only advisable:
– outdoors;
– for short-term operation (up to a maximum of 30 minutes);
– when wearing a dust respirator.
If no dust collector is used chips will built up inside the machine housing, and on the planer knives in particular. These built-up chips cause the planed surface to become rough. Therefore the chips need to be removed periodically.

Danger!
The rotation of the cutterblock causes the chips to be blown through the slot in the cutterblock cover.
Caution!
The slot of the cutterblock cover or an installed dust extraction connector must not be blocked by objects placed in the path of ejected chips.
Installing the dust extraction connector
**** Cutting hazard when touching the rotating cutterblock!
Accidental starting of the machine may cause serious injury.

7.1 Planing Work Pieces
The thickness planer can remove a maxi mum of 1/8″ (3 mm) in a single pass.
However, this depth of cut may be used only:
– with very sharp planer knives;
– when planing soft wood;
– when the maximum work piece width is not used.
Otherwise there is a risk of overloading the machine.

• It is strongly recommended that you make several passes at a moderate depth of cut, to achieve the desired work piece thickness.

Note:
The ideal depth of cut to be used depends on a number of factors, such as type of wood, work piece width or the state of dryness of the wood.
If you are planing mainly very wide (13 inch (330 mm)) work pieces, the motor is subjected to heavy loads.

• Plane narrow work pieces inbetween, or take a break to relieve the motor.

Work piece dimensions

• Do not work work pieces which are shorter than 14 inch (356 mm). With shorter work pieces there is a risk of kickback!
• Do not work work pieces which are shorter than 3/16 ” (5 mm). The cutterblock head cannot be set lower.
• Work only work pieces which are wider than 3/4 ” (19 mm).
• Use extra work piece supports for work pieces which are longer than 5 feet (1500 mm).
• Never thickness several work pieces at the same time. Risk of personal injury if individual pieces are uncontrolled caught by the cutterblock.

1. Fold down both infeed and outfeed table.

2. Set the planing thickness with the crank (53). The planing thickness is indicated by the scale (54).
   Risk of kickback!
   Adjust the planing thickness only when the cutterblock is at standstill!

3. Start motor (press green switch button).
   Risk of injury!
   • Never reach with your hands into the machine when guiding the workpiece!
   • Guide a work piece on the outfeed side if it has been fed so far into the thicknesser that it can no longer be safely guided from the infeed side.
   • Never force the work piece into the machine by pushing or shoving.
   The machine will draw the work piece in automatically with the infeed roller.

4. Slide work piece slowly over the infeed table. It will then be automatically fed through the thicknesser.

5. Guide work piece straight through the thicknesser.

6. Switch machine off if no further planing is to be done immediately afterwards.

Planing with the final thickness stop

1. Set lock lever fully to the left, into the position marked .
2. Raise cutterblock head and set to a planing thickness of more than 1 3/4″ (44 mm).
3. Set the final thickness stop (55) to the desired thickness of the workpiece.
4. Lower the cutterblock head, until it is stopped by the final thickness stop. Possibly the work piece needs to be planed down to a thickness which will permit it to be planed down to the final thickness in the last pass.
5. Set lock lever fully to the right, to the position marked .
6. Start motor (press green switch button) and plane the work piece.

Care and Maintenance

Prior to all servicing:

1. switch machine OFF;
2. Wait until the cutterblock has come to a complete stop.

8. Check machine for parts that may have worked loose; fasten any loose parts properly, where necessary.

8.3 Adjusting the Final Thickness Stop

1. Using the final thickness stop, plane work piece to the desired stop measure.
2. Measure the actual stop measure (= work piece thickness) of the workpiece.

If readjustment of the final thickness stop is necessary:

1. Unplug power cable.

2. Set lock lever fully to the left, into the position marked .

3. Loosen Phillips head screw (66) securing the crank of the height adjustment, but do not remove it.

4. Removing the side cover (68):
   – Remove both Allen head screws (67) (metric, 6 mm).
   – Lift the machine’s upper part at the carrying handle, then carefully remove the side cover (68).

5. Lower the cutterblock head, until the final thickness stop (70) makes contact with the stop screw (69). When doing so, the final thickness stop must be set to the above set stop measure.

6. Loosen the lock nut of the stop screw (69) with the open jaw wrench (metric, 10 mm), and adjust the stop screw by the difference between the set stop measure and the measured actual thickness of the work piece.

7. Secure the stop screw (69) in position with the lock nut.

8. Reinstall the side cover (68) and fasten with the two Allen head screws (67).

9. Retighten the Phillips head screw (66) securing the crank of the heighadjustment, handtight only.

8.4 Checking and Replacingthe Carbon Brushes
Both front and rear carbon brushes should be checked every 10 to 15 operating hours.
Worn carbon brushes are recognizable by:

• intermittent operation of motor;
• Interference in radio and TV reception while the motor is running;
• motor stalling.

To check or replace carbon brushes:

1. Unplug power cable.

2. Fold down both infeed and outfeed table.

3. Remove the carbon brush on the infeed side of the machine: unscrew the plug (71) from the motor housing with a suitable screwdriver.
   Note:
   The rear carbon brush is located on the opposite (outfeed) side. To remove the rear carbon brush, the dust extraction adaptor and the cutterblock cover need to be removed first.

4. Pull carbon brush (72) out and check. Each carbon brush should be at least 1/4″ (6 mm) long.

5. Fit intact or new carbon brush (72) into the carbon holder (73). The two lugs on the sides of the small metal plate must fit into the grooves in the brush holder.

6. Replace the plug (71).
   Note:
   After replacement of the rear carbon brush, both the cutterblock cover and the dust extraction connector must be reinstalled and securely fastened.

7. Check the functioning of the machine.

8.5 Storage

1. Unplug and stow away the power supply cable in the pocket on the underside of the outfeed table.
2. Swing both infeed and outfeed table up.
3. Store machine in a way that
   – it cannot be used or tempered with by unauthorized persons, and
   – nobody can get hurt by the stored machine.

Caution!
Do not store machine unprotected outdoors or in damp environment.
8.6 Transport

1. Unplug power supply cable.
2. Unscrew and remove the dust extraction connector (74).
3. Swing both infeed and outfeed table up.
4. Stow away the power supply cable in the pocket on the underside of the outfeed table.
5. Transport machine holding it by the carrying handles on its sides.

Caution!
Never store the machine outdoors, in unprotected areas or in damp or wet locations.

Troubleshooting

• The values stated are emission values and as such do not necessarily constitute values which are safe for the workplace. Although there is a correlation between emission levels and environmental impact levels, whether further precautions are necessary cannot be derived from this. Factors influencing the actually present environmental impact level in the workplace include the characteristics of the work area and other noise sources, i.e. the number of machines and other neighbouring work processes. Also, permissible workplace values may vary from country to country. This information is intended to assist the user in his estimate of hazards and risks.
