Noise emission
Notes concerning noise emission
Given that there exists a relationship between noise level and exposure times, it is
not precise enough to determine the need for supplementary precautions. The
factors affecting the true level of exposure to operators are clearly the amount of
time exposed, the characteristics of working environment other sources of dust and
noise etc. For example, adjacent machines in other words the level of ambient
noise. It is possible that exposure level limits will vary from country to country.

Receiving your machine.
Note. It is probable that your machine will be delivered by a third party. Before you
unpack your new machine, you will need to first inspect the packing, invoice, and
shipping documents, supplied by the driver.
Insure that there is no visible damage to the packing, or the machine. You need to
do this prior to the driver leaving. All damage must be noted on the delivery
documents and signed by you, and the delivery driver. You must then contact the
seller, [Laguna Tools] within 24 hours.
Introduction to jointer.
The jointer is designed to give you years of safe service. Read this owner’s manual
in its entirety before assembly or use.
The jointer is generally defined as a machine that cuts planks of wood flat, and
smooth. The machine achieves this by the plank being pushed along a flat table,
and passing the plank over a revolving cutter head.
There are many types of cutter head, and this machine uses an inserted cutter
type. The insert cutters main advantage is to reduce tear out of the grain, but the
finish is not as smooth as the parallel blade system. It is well within the capabilities
of a belt sander to give a professional finish to the jointed plank.
The parallel blade system, gives a finish without the lines that the insert cutter
system gives, but, is susceptible to tear out, especially on planks with knots. On
balance, it is better to use a machine with the insert cutters than the parallel
blades, as it greatly reduces the risks of having to scrap valuable wood, or
spending excessive time sanding tear out marks.
Additional instructions for the use of the jointer.
Like all machines, there is danger associated with the machine. Injury is frequently
caused by lack of knowledge or familiarity. Use this machine with respect. If normal
safety precautions are overlooked or ignored, serious personal injury may occur.
1. Kickback.
"Kickback" is when the work piece is thrown off the jointer table by the cutter head.
Always use push blocks and safety glasses to reduce the likelihood of injury from
“kickback.”. The "kickback zone" is the path directly through the end of the in feed
table. Never stand or allow others to stand in this area during operation. If kick
back occurs, severer injury may occur.

7
2. Cutter head alignment.
To reduce the possibility of kickback, keep the top edge of the out feed table
aligned with the cutter head insert at top dead centre (TDC).
3. Push blocks.
The cutter heads are extremely dangerous and you must never pass your hands
over the cutter head. Always use push blocks whenever surface planning.
4. Supporting the work.
Only make cuts if the work piece is stable and never attempt to cut unstable
planks, or injury may occur.
6.Cutting depth.
Never exceed the maximum cutting depth as stated in the specification for your
machine. It is far better to take several small cuts rather than large cuts.
7. Direction of cut
Jointing against the grain or jointing end grain is dangerous and could produce
chatter or excessive chip out. Always joint with the grain.
8.Guards.
Guards are designed to reduce the risk of injury. Always use the guards. If it is
imperative to use the machine without the guards, [Rabbeting] always replace the
guards.
9.Cutting direction.
Only cut from the in feed table to the out feed table, and always complete the cut.
Do not stop the wood progress until the job has cleared the cutter head completely.
Only cut with the grain or at a slight angle to the grain.
10. Stock.
Your safety will be greatly enhanced if you only use good lumber. Only work with
lumber after you have inspected it completely. Staples, Nails Loose knots and any
other metal in the plank will damage your cutter head and could case injury and or
fire. If you have any question about a piece of lumber, do not use it.
What you will receive with the jointer.
1. Spare cutter teeth.
2. Spare cutter screws.
3. Tools.
4. Push block.
Parts of the jointer.
The jointer doe’s not have many parts. The major parts are discussed in this
manual. If you are not familiar with the jointer, take the time to read this section and
become familiar with the machine.

Out feed Table.
The function of the out feed table is to support the job once it has been machined
by the cutter head. The out feed table must be adjusted level with the cutter head
teeth at top dead centre [TDC].
In feed Table.
The in feed table is adjusted to suit the depth of cut that is required.
Note. Never exceed the maximum depth of cut specified for your machine. It is far
safer to take many small cuts rather than one large cut.
Fence.
The fence is used to keep the job square to the cutter head and is also used to
produce angle cuts on the edges of panels. The fence can be adjusted from 90 to
45 degrees.
Cutter head Guard.
The guard is there to protect you. Always adjust the guard to expose only the
minimum amount of cutter to suit the job width.
Electrical cable.
Note. The machine may not be supplied with a plug as the plug type will depend
on your electrical supply.
Table height adjusting handles.
The hand wheels adjusts the tables to the required height.
Body.
The body of the machine supports the table etc. It is manufactured from heavy
gauge steel and provides a heavy base that is designed for rigidity.
Mobility kit.
The mobility kit allows the machine to be moved to various locations within your
work area.

This plate is mounted on the back of the machine.
Where to locate your Machine.
Before you unpack your machine, select the area where you will use your machine.
There are no hard and fast rules for its location, but, below are a few guidelines.
1. There should be an area around the machine suitable for the length of wood that
you will be machining.
2. Adequate lighting. The better the lighting, the more accurate and safely
you will be able to work
3. Solid floor. You should select a solid flat floor, preferably concrete or
something similar.
4. Close to power source and dust collection.
Unpacking your machine.
To unpack your machine, you will need tin snips, knife and a wrench.
1. Using the tin snips, cut the banding that is securing the machine to the
Pallet [if fitted].
WARNING: EXTREME CAUTION MUST BE USED BECAUSE THE
BANDING WILL SPRING AND COULD CAUSE INJURY.
2. Remove the box from the Jointer. The parts will be packed at the side of the
plainer.
Note. The machine is heavy, and if you have any doubt about the
described procedure, seek professional assistance. Do not attempt any
procedure that you feel is unsafe or that you do not have the physical capability of
achieving.
Note. To remove the plainer from the box you will need 2 or more people.
3. Slide the plainer so that it overhangs the pallet. Tip the plainer so that it touches
the floor. Slide the pallet from under the jointer, and lower the jointer to the floor.
Assembly & set up.
Mobility kit.
Mobility clamp screw
Mobility wheel
The mobility wheels come pre-fitted to the base of the machine.
The wheels are locked by tightening the clamp screws on the outside of the body.

10
Fitting the on / off switch.
Fit the on / off assembly to the side of the body as shown.
The jointer is now fully assembled but before the machine is connected to the
electrical supply the following checks and adjustments must be carried out.
1. Move the jointer to the location that it will be used.
2. Check that the cutter head can rotate freely and that the teeth do not contact
either the in or the out feed tables.
3. Check that the guard is covering the cutter head and that is free to move and
spring back once released.
4. Check that all tools have been removed from the machine.
Connecting the electrical supply.
Note. A qualified electrician must carry out the
installation.
Ensure that the main supply corresponds with
that of the machine [Single phase 220 V].
It is recommended that you use a 30-amp mains
breaker.
If you need a longer cable than that
supplied on the machine, you can connect a
new cable into the internal power termination.
Note. The machine is not normally supplied with
an electrical plug, as the type of plug will be
dependent on the installation.
Connecting the dust collection.
Connect a 4” flexible hose
between the dust hose connector
and your dust collector.
Once fitted pull on the hose to
ensure that the connection is
tight.
Note. You will need a dust
collection system with a minimum
of 1000 cubic feet per minuet
capacity. The stronger the dust
collection the better, as the
machine is capable of producing
a lot of waste.

Running and adjusting the machine.
Cleaning the machine.
The machine is shipped with the none painted surfaces protected from rust by a
film of grease.
The grease must be removed with WD40 or similar, as it attracts saw dust and dirt.
The surfaces should then be coated with a Teflon lubricant or similar. Teflon tends
to dry and will not attract saw dust and dirt.
Test Run.
Now that the assembly is complete it
is time to conduct a test run.
During the test run you will check the
following points.
1. Motor starts and runs smoothly.
2. That the stop button, function
correctly.
Before you run the machine check
the following.
1. All the tools have been removed
from the machine.
2. That the guard is in place.
3. You are wearing the appropriate
safety equipment.
5. You have read and understood the instruction manual.
Note. If any of the below functions fail to operate correctly, the fault must be
corrected prior to continuing to the next test. Any investigation to find or correct a
fault must be conducted with the power disconnected.
1. Turn the power on, with the key switch.
2. Start the machine by pressing the green start button.
The machine should run smoothly with little or no vibration.
3. Press the red stop button. The machine should slow down and stop.
Note. The red stop button has to be re-set by twisting until it pops out. If the
machine fails to start, check that the stop button is re-set in the out position.
Adjustments.
Note. The machine has had all its functions calibrated at the factory but due to
shipping conditions some movement may have taken place. This is unavoidable
and it is therefore recommended that the following checks are made prior to
starting production. As the machine is used some functions may move and it is
therefore good practice to know the process for adjusting the machine prior to
production.
Adjusting the drive belt.
Key switch
Off button On button
Motor Adjuster
Cutter head pulley

Adjust the belt so that there is approx 3/16 in deflection when pressed with
moderate finger pressure.
The drive belt should be checked after running the machine for approximately 10
hours. The belt beds into the pulleys, and will slacken off slightly. If is not adjusted,
slippage may accrue and this will cause early belt failure. There should be a 3/16”
deflection when the belt is pressed with moderate finger pressure.
Note. To access the motor and drive belt, remove the side and top panel.
Note. Disconnect the power to the machine prior to conducting machine
adjustments or repairs.
Setting the out feed table to the cutter head.
The out feed table must be level with the teeth of the cutter head when the teeth is
at top dead centre [T.D.C.]
Out feed table
Straight edge Cutter head
1. Rotate the cutter head so that the teeth are at the T.D.C. position.
2. Place a straight edge on the out feed table over the cutter head and check that
the teeth just touch the straight
edge.
Note. This has to be checked at
both sides of the table.
Setting the in feed table.
1. Place a straight edge so that it
is equal on both the in feed and
out feed tables.
2. Bring the in feed table up so that
the straight edge is even on both
tables.
3. Check that the table is lined up
with the scale at “0”.
Fitting teeth to the Sher tec cutter
head.
The carbide cutter head [Sher Tec]
has multiple teeth which have 4
cutting edges. The teeth can be
rotated as follows, when they are
blunt or damaged.
Note. You will notice that each
cutter tooth has a registration dot to
enable you to ensure that the teeth
are moved round in the same
direction.
1. Loosen the tooth with the special
allen key.
2. Lift the tooth and rotate to the new cutting face.
Scale
Registration dot

13
Note. Take special care to clean the tooth and its mating surface. Any dirt or
sawdust that is trapped under the tooth will cause it to be at a different height to the
other teeth, and degrade the surface finish when you start machining. This will
result in you having to take all the teeth out and clean the teeth and the mating
surfaces again. This is very frustrating and a waste of time. Take your time and
ensure that you are very thorough with cleaning.
3. Lower the tooth into the cutter head and clamp with the allen key.
Note. Only move all the teeth to a new cutting edge. Do not move less than all the
teeth.
Note. The carbide cutter head will has several advantages over the parallel blade
type cutter head.
1. The teeth are carbide and will last longer than high speed steel parallel blades.
2. There is less chance of tare out.
The disadvantage is that they are initially more expensive and the surface finish is
slightly wavy. This is caused because the
teeth have a very slight radius. This
waviness is easily removed by a light
sanding.
Adjusting the fence.
The fence has 2 adjustable stops. One
for 45 degrees, and the other stop for the
90 degree position.
The fence is clamped in the angle
position with the angle clamp handle. To
adjust the fence, loosen the clamp
handle, move to the required position,
and re clamp.
The stops do not come pre set, and to
set, follow the guide lines below.
To move the fence across the jointer
table, loosen the clamp handle, move the fence with the forward back handle to the
required position, and re clamp.
Adjusting the 45 degree stop
90 degree stop

2. Move the flip stop to the
position shown.
1. Adjust the fence to 90
degrees using a set square,
and lock in position.
3. Adjust the stop screw so that
it touches the flip stop, and lock
in position with the lock nut.
4. Unlock the fence and move.
Move the fence back to the 90
degree stop and lock in
position. Check that the fence
is at 90 degrees. If the fence is not at 90 degrees, readjust.
Maintenance
As with any machine, to ensure optimal performance you must conduct regular
maintenance.
Daily checks.
1. Clean the machine and lubricate unpainted surfaces with a Teflon lubricant.
Wipe off any excess and buff with a dry polishing cloth. This will reduce the likely
hood of rust forming and reduce the friction on the tables as the wood is machined.
2. Check cutter teeth for chips and dullness.
3. Generally inspect the machine for damage and loose or warn parts.
Weekly checks.
1. Clean the cutter head.
2. Check cutter teeth for chips and dullness.
3. Generally inspect the machine for damage and loose or warn parts.
4. Check the dust extraction for blockages and any large bits that could cause
blockages.
Monthly checks.
1. Check the motor drive belt for wear, splits and cuts.
2. Clean the motor compartment and the motor to ensure that the motor cooling
fins work efficiently.
3. Generally inspect the machine for damage and loose or warn parts.
Note. It is recommended that you use a Teflon based lubricant.
Drive belt replacement.
Note. Disconnect the power to the machine.
1. Remove the side cover.
2. Loosen the motor adjustor.
3. Remove the drive belt.
4. Fit the new belt.
5. Re-tension the belt. There should be a 3/16” deflection when the belt is pressed
with moderate finger pressure. Tighten the motor clamping bolts.
6. The drive belt should be checked after running the machine for approximately 10
hours. The belt bed into the pulleys, and will slacken off slightly. If it is not adjusted
slippage may accrue and this will cause early belt failure. There should be a 3/16”
deflection when the belt is pressed with moderate finger pressure.
7. Refit the side cover before running the machine.
Flip stop Stop screw

15
Lubricating the machine.
Note. All the bearings are sealed for life and do not require lubrication. If a bearing
is noisy, do not try to re lubricate but replace it.
Note. It is recommended that you use a Teflon based lubricant as it tends to dry
and therefore will attract less saw dust and dirt.
