Maintenance And Inspection - Jet Tools JWBS-10 Mode D'emploi

Use a square (E, Figure 30) placed on the table and against
the blade, to verify that table is 90º to blade.
If an adjustment is necessary, tilt table up to access table
stop (C, Figure 29).
Loosen jam nut (D, Figure 29) and turn table stop in or out
to raise or lower the stop. Tighten the jam nut to hold table
stop in place.
Tilt table back to level, letting it rest against the stop and
confirm table is 90º with the blade as described in step 3.
For left tilt down to 5º, the table stop (C, Figure 9) must be
adjusted further.
7.8.2 Adjusting table tilt indicator
Set table at 90º with blade.
Confirm that table tilt indicator (F, Figure 30) points to zero.
If adjustment is required:
Slightly loosen screw securing indicator, adjust indicator to
point to zero; then re-tighten screw.
Test run:
Turn the wheels by hand and inspect the adjustments
made.
Start the machine with care.
Note:- When using the table at an angle always have the
rip fence on the lower side of the table to support the
workpiece.

8. Maintenance and inspection

General notes:
Maintenance, cleaning and repair work may only be
carried out after the machine is protected against
accidental starting by pulling the mains plug.
Repair and maintenance work on the electrical system may
only be carried out by a qualified electrician.
Clean the machine regularly.
NEVER USE WATER OR OTHER LIQUIDS TO CLEAN
THE MACHINE. USE A BRUSH.
Keep the ventilation slots of the motor clean to prevent it
from overheating.
Inspect the proper function of the dust extraction daily.
All protective and safety devices must be re-attached
immediately after completed cleaning, repair and
maintenance work.
Defective safety devices must be replaced immediately.
Inspect the correct blade tension regularly. Take away the
blade tension if the machine is not in use for a longer time
period.
Inspect the blade guide adjustment regularly.
Wheels:
The rubber tyre of the wheels must be cleaned regularly.
The upper wheel support must be lubricated regularly.
Table insert:
Replace a worn table insert.
The table insert may not project above table surface.
The table insert must be made out of cutable material (e.g.
wood, plastic, aluminium)
The table insert may not project above table surface.
Saw blades:
The servicing of saw blades should only be performed by a
trained person.
Only use sharp and properly set saw blades.
Replacing drive belt:
The belt tension must be inspected regularly.
Disconnect machine from power source.
Open upper and lower doors.
Remove saw blade as described.
Refer to Figure 31:
Remove tension on drive belt (L) by loosening the socket
head screw (13mm wrench required) on the back of the
cabinet that secures the motor.
Using snap ring pliers, remove snap ring (M) that secures
lower wheel (N) to shaft (O).
Slide lower wheel assembly off the shaft (O) which will
dislodge the belt (L). Discard the old belt.
Place new belt onto lower wheel pulley.
Reinstall lower wheel assembly by sliding it back onto the
shaft (O).
Reinstall snap ring (M).
Place new belt (L) partially around motor pulley (P) to get it
started, then turn wheel (N) by hand until belt is completely
seated on motor pulley (P).
Push the motor down to add tension to belt. The belt is
properly tensioned when moderate finger pressure on the
belt between the two pulleys causes a 1/2-inch deflection.
Tighten socket head screw on the back of the cabinet that
secures the motor.
Re-install blade.
Adjusting drive belt tension:
