8.0 OPERATION
8.1 Planing
The planing device consists of
- Feed table (A)
- Retrieve table (B)
- Knife shaft cover (C)
- Groove guide (D)
- Ball handle (E)
- Fixing bolt (F)
- Connecting bolt (G)
Prior to preparation work for thicknessing, the machine must come to a stop by main switch.
By screwing of the fixing bolt (F), the feed table (A) can be set for the required planing
thickness max.5 mm) with the ball handle (E). The retrieve table (B) comes on the
other side. The groove guide (D) swivels from 90° to 45° and can be set along the
whole length of the knives screwing the connecting bolt (G).
After completing the settings, the fixing bolt (F) and connecting bolt (G) must be screwed
firmly.
Working tips

5. Do not push the workpiece with finger tips or hands.
6. For small workpieces apply auxiliaries
7.. Check up for defects (nails, knots, etc.)
8. When surface of job is uneven, begin with the side from which less material is removed.
9. By sudden fall of working force e.g. power supply cut off, stop immediately the forward
feed. .
Planing of small workpieces
Take off the knives cover C and place it to the groove guide at distance equal to the width of
the workpiece (fig. l).
Press the workplece with the left hand agalnst tlie groove guide D and feed table A and feed
uniformly with the right hand (Fingers of both hands must be collected in fists and the thumbs
must be on the workpiece - fig. 2 and 3)
When planing small section jobs use an additional angular piece (to avoid accidents). The
knives shield C may serve as groove guide (fig. 4).

Holztech SD320
WWW.HOLZTECH.COM
For small jobs always use auxiliary supports.
Attention! The hands must never be placed on the knives shaft. The hand must always
be behind the knives shafts and the right hand must push the workpiece till
shortly before the shaft and then be withdrawn. The workpiece must always be
fed from above.
Planing of jobs of greater width.
•Shift forward groove guide so that the required planing space is free.
•Shift the knives shaft cover C to the groove guide (max. distance 8 mm) and increase job's
thickness.
•Push the job a little under the cover C and let the latter lay upon the workpiece (see
fig. 1).
•Press the job with both hands upon the feed table A and carefully feed towards the knives.
Hold tlie knives shafts cover with hand.
Proper handling
