ASSEMBLY OF PLANER TO BASE
Your 15” planer comes in 2 packing boxes, one contains
the assembled planer, the other, the assembled base,
in eed and out eed rollers plus dust chute.
The best way to li t the planer onto the base, is raising
the cutterhead, by turning the handwheel clockwise, Fig.
1(A) and placing 2 x 100 x 50mm boards on edge
onto the table to the le t and right o the machine. Then
lower the cutterhead till it grips the boards preventing
them rom slipping sideways. The protruding ends
become handles. You will require 1 it, healthy person
on each corner to li t the planer onto the base.
Align the 4 bolt holes at the corners, Fig. 1 (C) and with
the ront cover removed rom the base, insert bolts rom
underneath with the heads acing down, through both
the base and the planer, it nuts and washers provided
and tighten securely. Replace ront cover o base
ASSEMBLING TOP COVER AND DUST CHUTE.
Fasten top cover at 4 corners with screws provided, Fig. 2 (A).
The dust chute ramp must point to the back o the plan-
er.Place dust chute over the ramp o the top cover and tighten
the 3 hex head bolts on the top Fig. 2 (B) and 3 allen key
bolts underneath. Fig. 2 (C)
DUST EXTRACTION CHUTE
This machine is designed to be used with a dust extractor,
having a minimum o 600c m. I using the machine without a
dust extractor, the dust chust should be removed to prevent
clogging o the 100mm outlet. When the dust chute is
removed, the rotating cutterhead is easily accessible and pre-
cautions, such as a guard should be installed to prevent acci-
dental hand contact.
ANTIKICKBACK FINGERS (Fig. 3)
These ingers are designed to to prevent timber rom
being thrown back at the operator. No setting up is
required, however it is advisable to clean them occa-
sionally to prevent a build up o resin. Remember to dis-
connect machine rom power source be ore carrying out
any maintenance work.
A
DEPTH OF CUT ADJUSTMENT
To adjust the depth o cut you need to raise or lower the head
assembly which contains the cutterhead. Loosen the locking
knobs, Fig. 1 (B) and turn the handwheel clockwise to raise
the cutterhead and anticlockwise to lower it. When you have
set the machine to the required depth o cut, tighten the lock-
ing knobs .The gauge Fig. 1 (D) will tell you what inished size
that setting will give you.
The maximum depth o cut is 3/16” on stock narrower than
6”. A limiter Fig. 4 (A) is positioned to allow no more than
1/8” to be taken o a board wider than 6”.
NOTE: Do not attempt to machine timber less than 6mm
thick as the material may shatter.

REPLACING PLANER KNIVES
1. Remove top cover and dust chute.
2. Loosen 2 screws Fig. 5 (A) and pivot motor
assembly orward.
3. Loosen the screws that hold kni e locking bar in
place Fig. 6 (B).
4. Remove all 3 knives, locking bars and screws rom
the cutterhead.
5. Clean the kni e slots and bars,removing all traces
o sawdust and resin.
6. Replace the locking bars and put all three new
knives in position, tightening the locking bar
screws just enough to prevent the knives rom
alling out.
7. To adjust the height o the knives, you will need
the kni e setting gauge Fig. 7 (C). Place it on top o
the cutterhead.
8. To adjust the height o the blades, turn the allen
key screws located at each end o the kni e locking
bars Fig. 7 (E) anticlockwise to lower and clockwise
to raise them. The tip o the blades should just
brush the bottom o the setting gauge, this should
be even along the length o the blade.I there is no
movement o the blade when the adjustment
screws are moved, the screws holding the kni e
locking bars in place may be too tight to allow the
blades to move.
9. All three blades must be the same height, i not,
this will result in end snipe. (A dip at the end o
the board.)
10. Tighten the locking bar screws evenly. Double
check that all o them on all three blades are tight.
11. Replace top cover and dust chute and return
motor to correct position.
ADJUSTING HEIGHT OF CHIP DEFLECTOR
1. Access the inside o planer (see previous
instructions).
2. Loosen o the three slotted screws Fig. 7 (D)
that hold the nylon chip breaker in place.
3. Slide the chipbreaker down until it is about
0.5mm rom the ull arc o the blades in the
cutter block.CHECK THAT THE CHIP BREAKER
DOES NOT MAKE CONTACT WITH THE BLADES.
4. Tighten the screws and replace the top cover and
dust chute.
FEED ROLLER SPEED CONTROL
Your planer has 2 eed roller speeds 16 pm and
30 pm. For general purpose planing on so ter woods,
the aster speed is suitable, but or hard timbers, the
slower eed rate is more e ective. A slower speed puts
less strain on the motor. A slower eed rate will also
give a better inish as there will be more cuts per inch.
When changing the setting o the eed roller speed Fig.
8 (A) it is essential to have the machine running. Pull
the speed control lever all the way out or the slow
speed, 16 pm. The middle position is neutral,and push-
ing the lever all the way will give a eed roller speed o
30 pm.

ADJUSTING HEIGHT OF INFEED AND OUTFEED
ROLLERS
The in eed Fig. 9 (A) and out eed Fig. 10 (B) rollers
should be 1mm below the cutting circle o the cutter
block. To check this use your wooden gauge block and
a1mm spacer, such as a steel rule. The process is the
same or both the in and out eed rollers.
1. Position the wooden gauge block with the 1mm
spacer on top, Fig. 11 (A) & (B) under the cutter
head so the knives just brush the top o the spacer
when at their lowest point in the cutting
circle.Trans er the gauge block to underneath the
eed rollers minus the spacer Fig. 12 & 13. The
rollers should just touch the top o the gauge block.
2. I the rollers need to be adjusted, loosen the nuts
Fig. 9 & 10 (C), and turn adjusting screws Fig. 9 &
10 (D) until the rollers make contact with the gauge
block. Repeat process or the other end o the
rollers.

ADJUSTING TABLE ROLLERS.
The table rollers Fig. 15 (A) & Fig. 16 (A) are located on
the bed o the planer, and are designed to reduce ric-
tion as material passes over the table.They are present-
ly set or general purpose planing and are parallel to the
table.I you need to adjust them, higher is better or
rough sawn stock, and lower, or inished stock, lay a
straight edge Fig. 15 (B) across both rollers with a spac-
er Fig. 15 (C) the height you want the rollers set. The
adjustment screws Fig. 16 (D) are eccentric so take
care the rollers remain parallel to the table and each
other. One side o the planer, the screws turn clockwise
to raise or lower the rollers and on the other side they
turn anticlockwise to do the same.

ADJUSTING SPRING TENSION OF INFEED AND
OUTFEED ROLLERS.
In eed and out eed rollers are actory set and should
not need adjustment. I they do however, the spring ten-
sion o the in and out eed rollers must be su icient to
evenly eed the stock through the planer.It needs to be
even along the length o the roller and not be so tight
that it causes damage to the timber and jamming. I
adjustment is needed, do this by turning the screws
shown Fig. 14 (E) in eed rollers Fig. 14 (F) out eed
rollers at either end o each roller.

ADJUSTING CUTTERHEAD PARALLEL TO TABLE
The cutterhead casting and blades have been set paral-
lel in the actory. I your planer is not cutting parallel,
this may be caused by the blades not being properly
set.
I you can ind no other reason or the out o parallel,
check cutterhead casting is parallel by the ollowing pro-
cedure using your wooden gauge block.
1. A ter machine is disconnected rom power source,
put gauge block on the table under the casting.
Lower head so it just touches the gauge block
Fig. 17.
2. Move block to the opposite end to check i it is the
same distance rom the casting to the block.
Fig. 18.
3. Repeat process at rear o machine.
4. I the head casting is not parallel to the table, tilt
machine on its’ side and loosen the bolt Fig. 19 (A)
and loosen bolt Fig. 19 (B). You will need to adjust
the idler sprocket assembly Fig. 19 (C) to release
the tension on the chain.
5. Remove chain rom sprocket on corner o
headcasting that needs adjustment.
6. Turn sprocket gently by hand to bring that corner
into line with the others. One or two teeth should be
enough. Clockwise will decrease the table distance
rom the headcasting anticlockwise will increase it.
7. Replace chain without disturbing the new setting.
Put idler sprocket assembly back into place and
tighten bolts.

ADJUSTING BELT TENSION
DISCONNECT POWER SOURCE FIRST!!!
Remove the pulley guard Fig. 22 (C) by taking out the 4
ixing screws Fig. 22 (D). Loosen the slotted screws Fig.
23 (E) and lever up the motor by placing a piece o wood
under the motor plate.Retighten the slotted screws and
replace the pulley cover.
LUBRICATION
The oil should be changed once a year in the gear box
using extreme pressure oil.
The gear box drain plug is shown at le t Fig. 20 (A). The
oil ill and level plug is at the top o the gear box.
Note our raising screws Fig. 21 (B) in the outside
columns o the machine should be lubricated using a
grease.
