Safety devices

Anti-kickback lock

The anti-kickback lock (33) prevents the work piece from being thrown back against the operator by the rotating cutter block.

• All fingers of the anti-kickback lock must end in a point on the underside.
• All anti-kickback fingers must automatically return to their rest position (downwards).

Cutterblock guard extrusion

The cutter block guard extrusion (36) prevents the rotating cutter block from being touched from the top when surface planing.

• After loosening the lock lever (35) the cutterblock guard extrusion is adjusted to the workpiece width.
• With the height adjustment screw (34) the cutter block guard extrusion is adjusted to the workpiece height. The height of the cutterblock cover extrusion can be adjusted from 0 to 85 mm for surface planing.

For effective protection, the cutter block guard extrusion must always be set against the workpiece. When guiding the work piece the hands slide over the cutterblock guard extrusion.

Chip chute

When thickness planing the chip chute (37) serves as cutterblock guard. For this purpose the chip chute (37) is folded upwards and the adjustment screw (38) is turned anti-clockwise to the end position (chip chute is secured).

Operating Controls

ON/OFF Switch

• Switching on = press green switch.
• Switching off = press red switch.

Undervoltage relay
An Undervoltage relay trips in the event of a voltage failure. This prevents the automatic restarting of the machine when power is restored. To restart the machine after a power failure, the green ON switch button must be pressed again.

Overload protection
The planer/thicknesser has integrated overload protection. It shuts the machine down if the motor heats up too much. To restart the machine:

1. let the motor cool down (approx. 10 minutes);
2. press the green switch button .

Infeed table height setting (when operated in surface planer mode)
With the height setting for the thicknesser bed the planing thickness (= thickness of the workpiece after plan-ing) is set when the machine is used for thickness planing.

• One full turn of the crank changes the height position of the thicknesser bed by 3 mm.
• er pass a maximum of 3 mm mate-rial can be removed.
• ork pieces of max. 160 mm thickness can be thickness planed.

Infeed table height setting (when operated in surface planer mode)
With the height setting (39) for the infeed table the depth of cut is set when the machine is used for surface planing.

• One graduation mark on the scale at the side of the infeed table (40) corresponds to 1 mm chip removal.
• Per pass a maximum of 3 mm of material can be removed.

Fence profile
The fence profile (41) provides lateral support for the work piece when surface planing.

• After loosing the clamping lever (43) the fence profile can be adjusted to the width of the work piece.
• Loosen the lock lever (42) to tilt the fence extrusion to a maximum of 45°.

Assembly

Modification of the machine or use of parts not tested and approved by the manufacturer can cause unforeseen damage.

• Assemble machine exactly as per these instructions.
• Use only th eparts supplied with the machine as standard equip-ment.
• Do not change any parts.

2. Fasten fence carrier support bracket (60) with two hexagon head screws (59) to infeed table.
3. Attach fence carrier to fence carrier support bracket again.
4. Slide two carriage bolts (62) into the fence extrusion (63) and attach to fence carrier with two self-locking hexagon nuts (58).
5. Fit extrusion end caps (64) to both ends of the fence extrusion.
6. Screw the cover plates (55) together and fasten to fence carrier using two crosshead screws (56).
7. Adjust the two set screws so that the positive stops of the jointer fence are set exactly to 45° and 90° (use try and mitre squares).

Power-supply connection
Danger!

High voltage
Operate in dry environment only. Operate machine only on a power source matching the following requirements (see also “Technical Specications”):

• fuse protection by a residual current operated device (RCD) of 30 mA sensitivity;
• outlets properly installed, earthed or grounded, and tested;
• 5-wire three-phase outlets with neutral lead.
• When a dust collector is used it must also be properly earthed.

Position the power supply cable so it does not interfere with the work and is not damaged. Protect power supply cable from heat, aggressive liquids and sharp edges.Use only extension cables with a sufficient lead cross section. Do not pull on the power supply cable to  unplug it.check the direction of rotation! (machines with 3-phase motor only): Depending onthe phase sequence the cutterblock may turn in the wrong direction. This can cause damage to the machine and workpiece. It is therefore necessary to check the direction of rotation after initial commissioning and every time the machine is connected to a different outlet. If the direction of rotation is incorrect the phases must be changed on the supply line or mains connection by an electrician.

Operation

The planer/thicknesser HC 260 can either be operated as surface planer or thickness planer:

Surface planer mode

Note:
Surface planing is used to level an uneven surface (= jointing), for example the edges of a plank.

• The work piece rests on top of the infeed table.
• The work piece is cut on the underside.
• The feed direction for the work piece is exactly opposite than that for thickness planing.

Work piece dimensions

Preparation
Danger!

Always unplug before servicing!

1.  Turn setting screw (65) clockwise to the end position.

2. Swing chip chute down.

3. Turn both left and right lock lever outwards.

4. Place outfeed table (66) on machine

   • both pins on the machine housing must engage in the lower slots of the outfeed table guide.
     Note: The pins must trigger the end switch. Only then the machine can be switched on.

5. Secure outfeed table (66) with both lock levers (67).

6. Set the infeed table to 2.0 to 2.5 mm by turning the height adjustment.

7. Crank thicknesser bed up to 120 mm height. 8. Place dust collector connector (this is not the chip chute mentioned in step 1!) below the infeed table into the machine. Observe correct position of the dust collector connector:

   • suction port points outwards;
   • slide dust collector connector in until the point of intersection of shaft and axis below the infeed table (arrow) is exactly above the matching seat of the dust collector connector.

8. Crank the thicknesser bed carefully up to secure the dust collector connector in position.

9. Connect a suitable dust collector to the suction port of the dust collector connector.

10. Cover the cutterblock with the cutterblock guard extrusion.

Note:
The dust extractor hood must be mounted. The dust extractor hood covers the knife shaft from below and must activate the limit switch to enable the machine to be switched on.

Danger!
Some types of wood dust (e.g. oak, ash) may cause cancer when inhaled: Use a suitable dust extraction unit when working in enclosed spaces:

• Fitting the outer diameter of the suction port (100 mm);
• air flow volume 550 m3/h;
• vacuum at suction port of thick-nesser 740 Pa;
• air speed at suction port of thick-nesser 20 m/s.

Caution!
Operation without a dust collector is only possible:

• Outdoors;
• if only a minimum of chips is generated (with narrow stock and little  chip removal);
• with dustrespirator.

Surface Planing and Edge Jointing
Danger!

• Risk of serious personal injury by rotating cutterblock! Always cover the part of the cutterblock that is not covered by the work piece with the cutterblock guard extrusion. Adjust the cutterblock guard extrusion exactly to the dimension of the work piece.
• Check the function of the cutter-block guard extrusion. Push the cutterblock guard extrusion downwards and release. After releasing the cutterblock guard extrusion has to spring back automatically to the set position. Do not operate the device with a defective cutterblock guard extrusion.
• Never reach with your hands under the cutter block guard extrusion when guiding the work piece!
• Use a feeding aid (push block) when planning small workpieces, which can not be guided with a sufficient safety distance to the cutterblock.
• Use the jointer fence when edge jointing to have safe lateral support and guiding. Use an auxiliary fence when planing thin or nar-row stock, to have your hands at a sufficient safety distance to the cutterblock.
• Use a stop block behind the workpiece for set-in work, to keep the workpiece from being thrown back against the direction of the feed.
• Use a workpiece support (e.g. roller stand) to keep long stock in balance.
• Do not pull the workpiece back over the unguarded cutter block!
• Use if necessary:
• Dust collection device (optional accessory); sliding wax to enhance the gliding of work pieces across the infeed and outfeed table.

1. Assume the proper operating position:

   • on the switch side;
   • head-on to the machine;

2. Set jointer fence as required.

   • with very sharp planer knives;
   • for soft woods;
   • if the full planing width is not utilized.
     Otherwise there is a risk of overloading the machine. It is best to make several passes to bring the work piece down to the desired thick-ness. Set depth of cut with starknob screw (68) on the infeed table.
     Note:
     The machine can remove 3 mm maxi-mum in a single pass. This measure, however, shall only be used:

3. Place work piece against jointer fence (if required, use auxiliary fence).

4. Adjust cutterblock guard extrusion:

   • Planing small edges (jointing): Push the cutter block guard extrusion (69) laterally to the workpiece.
   • Planing wide surfaces: Lower the cutter block guard extrusion (70) from above onto the workpiece.

5. Switching on the motor.

6. Push the work piece straigh across the infeed table. Keep fingers together and guide workpiece with the flat of your hand. Exert downward pressure on the work piece only in the infeed table area.

7. Switch machine off if no further thicknessing is to be done immediately afterwards.

Thickness Planer Mode

Note:
Thickness planning reduces the thickness of a workpiece with one already planned surface.

• The workpiece is fed through the thicknesser.
• The surface already planned flat rests on the thicknesser bed.
• The workpiece is cut on the upper side.
• The feed direction for the work piece is exactly the opposite that for surface planing.

   Note:
   For thickness planing the chip chute (77) serves as cutterblock cover. The chip chute must activate the limit switch, otherwise the machine cannot be started.

8. 8. If a dust collector is to be used, connect the dust collector connector’s suction port (75) to a suitable dust collector.

Danger!
Some types of wood dust (e.g. oak, ash) may cause cancer when inhaled: Use a suitable dust extraction unit when working in enclosed spaces:

• Fitting the outer diameter of the suction port (100 mm);
• Air volume  550 m3/h;
• vacuum at the suction port of the thicknesser
• 740 Pa;
• air speed at suction port of thicknesser 20 m/s.

Caution!
Operation without a dust collector is only possible:

• Outdoors;
• if only a minimum of chips is generated (with narrow stock and little chip removal)
• with dust respirator.

Thickness Planing

Danger!

• Entanglement hazard by the rotating feed rollers! Do not reach into the machine! Use a feeding aid (push stick) if you want to feed short stock into the thicknesser.
• Do not jam work pieces. Risk of kickback.
• Remove stuck stock only after motor has come to a complete stop and machine is unplugged.
• Guide a work piece on the out-feed side if it has been fed so far into the thicknesser that it can no longer be safely guided from the infeed side.
• Do not thickness plane more than two work pieces at the same time. In this case feed both work pieces near the outer edges of the thicknesser bed.
• Use if necessary: Dust collection device (optional accessory); sliding wax to enhance the glid-ing of work pieces across the infeed and outfeed table.

Caution!
There is a limit switch inside the machine. Take care not to damage the limit switch when feeding work pieces.

1. Assume proper operating position:

   • on the switch side;
   • head-on to the machine;

2. Set planing thickness with the crank.
   Note:
   The machine can remove 3 mm maximum in a single pass. This measure, however, shall only be used:

   • with very sharp planer knives;
   • for soft woods;
   • if the full planing width is not utilized. Otherwise there is a risk of overloading the machine. It is best to make several passes to bring the work piece down to the desired thickness.

3. To thickness plane stock which surfaces are not parallel, use suitable feeding aids (make fitting templates).

4. Switching on the motor.

5. Feed work piece slowly and straight into the thicknesser. It will then be automatically fed through the thicknesser.

6. Guide work piece straight through the thicknesser.

7. Switch machine off if no further thicknessing is to be done immediately afterwards.

Care And Maintenance

Danger!
Prior to all servicing:

• Switch off the machine.
• Disconnect the mains plug.
• Wait until machine has come to a complete stop.

Replace defective parts, especially of safety devices, only with genuine replacement parts. Parts not tested and approved by the manufacturer can cause unforeseen damage.

After all servicing:

• Put back into operation and check all safety installations.
• Make sure that no tools or other parts remain on or in the machine.

Repair and maintenance work other than described in this section should only be carried out by qualified specialists.

Replacing Planer Knives

Note:
Blunt planer knives are recognizable by:

• reduced planing performance;
• increased risk of kickback;
• motor overloads.

Danger!
Risk of personal injury by cuts from the planer knives! Wear gloves when changing planer knives.
To remove the planer knives:

1. Disconnect the mains plug.

2. Remove fence.

3. Raise cutterblock guard extrusion fully and pull extrusion fully outwards.

4. Turn the four hexagon head screws of the planer knife lockbar fully in (wear gloves!).

5. Remove planer knife lockbar (79) with planer knife (78) from the cutterblock (80).

6. Clean all surfaces of cutterblock and planer knife lockbar.
   Danger!
   Do not use cleaning agents (e.g. to remove resin residue) that could corrode the light metal components; the stability of the light metal components would be adversely affected. To install the planer knives: Note: If you use planer knives having an edge on both sides you simply need to reverse the knives, provided the other edge is sufficiently sharp.
   Danger!

   • Use only suitable planer knives (see “Technical Specifications”)
   • unsuitable, incorrectly mounted, dull or damaged planer knives can work loose, or increase the risk of kickback considerably.
   • Always replace or reverse both planer knives.
   • Install planer knives using only genuine replacement parts.

7. Place fresh planer knife on planer knife lockbar as shown. Both pins of the planer knife lockbar must fit into the holes (81) of the planer knife.

8. Place the planer knife lockbar (83) with the planer knife (82) into the cutterblock. Ensure that the knife does not slip off the pins of the planer knife lockbar.

9. Turn the four hexagon head screws in the planer knife lockbar out, until lock bar (85) and knife (84) can still just be moved along the axis of the cutterblock.

10. There are two ways to check the projection of the knives:

    • With the setting gauge (86) (under the prevailing regulations governing safety at work this must be supplied with the machine).
    • Place planer knife setting gauge on cutter block as shown. The knives must project so much that they touch the setting gauge. This check must be performed on both planer knives and at both ends of the cutterblock.
    • Use an aluminum straightedge (87) (this is more precise than using a setting gauge).
    • Place aluminum straightedge as shown over outfeed table and cutterblock.
    • Turn cutterblock by hand one turn against the direction of feed.
    • The planer knives are set correctly if the straight edge is moved forward 4 to 6 mm by the turning cutter block. This check must be performed at both ends of the cutter block.

11. To set the knife projection, turn the grub screws in the planer knife lockbar with a 3 mm Allen key as required.

12. To tighten, turn the four hexagon head screws of the planer knife lockbar fully out. To prevent distortion of the planer knife lock bar start with the screws in the center, then tighten the screws closer to the edges.

Danger!

• Do not extend tool when tightening the screws.
• Do not tighten bolts by striking the wrench.
• Return cutter block guard extrusion to its starting position.
• Mount fence.

Repairs

Danger!
Repairs to electrical tools must ONLY be carried out by qualified electricians! Contact your local Metabo representative if you have Metabo power tools requiring repairs. See www.metabo.com for addresses. You can download a list of spare parts from www.metabo.com.

Environmental Protection

All packaging materials are recyclable. Scrap power tools and accessories contain large amounts of valuable resources and plastics that can be recycled. The instructions were printed on chlorine- free bleached paper.

Troubleshooting

Danger!
Before carrying out any fault service or maintenance work, always:

1. Switch the machine off.
2. Wait until the saw has come to a complete stop.
3. Disconnect the mains plug.

Cutting hazard when touching the rotating cutter block! Unintentional startup of the machine may lead to serious injuries.
Risk of burning!
Shortly after working the planer knives may be hot – Let the device cool down before rectifying any malfunction.
Danger!
After each malfunction rectification: Put it back into operation and check all safety installations.

The motor does not run:

• Undervoltage relay tripped by temporary voltage failure.
  • Start again.
• No mains voltage.
  • Check cables, plug, outlet, and mains fuse.
• The motor has overheated, e.g. due to blunt planer knives, overloading or chip buildup.
  • Remove the cause for overheating and allow to cool down for approx. 10 minutes, then start again.
• Contact pins of the outfeed table or dust chute have not engaged in the limit switch.
  • Correctly install the outfeed table or dust chute, respectively. If necessary, adjust contact pins.
  • When thickness planing: Check if the set screw of the chip guard is turned to the end position and correct if necessary. Only then the contact switch is activated and the machine can be switched on (see chapter 6.3 “Operation as thickness planer”).
  • When surface planing: Check if the chip extraction guard is mounted correctly. Only then the contact switch is activated and the machine can be switched on (see chapter 6.1 “Operation as surface planer”).

• 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 work- place values may vary from country to country. This information is intended to assist the user in estimate of hazards and risks.
