Surface Planer/Thicknesser - Mortising Machine - Jet RDJ 310-M User Manual

Surface planer/Thicknesser - Mortiser
Safety precautions must be taken
1. Make sure that no drill bit is left in the drill head.
2. Check that the planing knives are in the right position and correctly tensioned. It is of utmost importance
that the planing knives are tightened accurately and firmly. Otherwise, the knives will inevitably be
thrown off the planer shaft when the machine is started.
Changing and adjusting the blades
1. Open both surface planing tables and remove the old blades after releasing the locking bolts (Fig. 9.1).
2. Clean the clamping surfaces of the planer shaft. Make sure that the springs (Fig. 9.2) under the blades
are not jammed in the bores.
3. The height of a sharpened blade (Fig. 9.3) should be at least 20 mm.
4. Adjust the cleaned blades (Fig. 9.3) using the adjustment template provided (Fig. 9.4) (Part No. X428).
5. Tighten the locking screws (Fig. 9.1) with the supplied spanner, starting from the centre of the shaft and
working outwards.
6. Start the machine for a test run, then tighten the blades fully.

Table adjustment
1 The planing outfeed table should be set at the same height as the blades.
2 To do this, use a wooden batten placed on the outfeed table just above a blade. Both tables have a
clamping lever (Fig. 11.1) and an adjusting screw (Fig. 11.2). To adjust the height, the table must be
set correctly using the adjusting screw.
3 During this adjustment, manually turn the planer shaft until the knives are just in contact with the
underside of the batten.
4 Once the height has been set, the table must be locked again.
5 Chip removal is controlled by adjusting the height of the feed table and should not exceed 4 mm.
6 Lock the table once the chip removal rate has been set.
7 The tables are opened by releasing the clamping levers and opening the tables.
8 Before closing the infeed and outfeed tables, keep in mind that the safety latch must be pulled down
(Fig. 11.3). (Fig 14)
9 When unfolded, both tables are protected against unintentional closing by this safety device.
Locking of the surface planing tables on RDJ 310
Both planing tables lock automatically when tilted to the open position for thicknessing.
1 Swing the guard/evacuation device onto the planer shaft (Fig. 12+13) and secure it with the locking
