MAINTENANCE
Risk of serious injury if maintenance is neglected.
The CH3 is easy to maintain, as it is largely rust pro-
tected. All cutter bearings and motors are completely
maintenance-free. Required maintenance is specified
below.
Make sure that the power is off before opening the
planer's safety hatch or removing any protective
cover.
Tip:
It is advisable to use compressed air to blow the
machine clean every time you open the safety hatch
on the machine.
When using the machine:
Clean the machine from chips. In particular, check
that chips have not accumulated under the machine.
This can in that case prevent the motors from cooling
and lead to motor failure or, in the worst case, fire.
Check that all chip couplings are connected to the
chip extractor.
Check that all feed rollers can move vertically.
The table should be regularly cleaned and treated with
lubricant, e.g. low viscosity oil or wax. Logosol's lub-
ricant is especially made for woodworking machines.
Avoid getting lubricant on the feed rollers.
After each use:
Clean the machine from chips. Also check chip coup-
lings and hoses. Remove chips that have accumulated
under the machine.
Clean the cutters and feed rollers from resin and
packed chips with mineral spirits.
Check that chips have not accumulated behind the
top cutter's right bearing housing. In this is the case,
clean with a flat tool, e.g. a steel ruler.
Check that chips are not packed into the springs under
the bearing housings of the feed rollers.
Clean the table and treat it with lubricant.
Clean and lubricate the three pressure rollers so that
they move freely.
Check belt tensions.
Check that all screws/bolts and bolted joints are secure.
Check that all cables and connections are in good
condition.
Check the function of the lights by pressing the emer-
gency stop and then the power start button.
Chips can be packed under the sprung bearings
of the feed rollers, which would impair feed and
increase the risk of ejections.
Make sure that the following parts are well
lubricated. ISO VG 68 chain oil is recommended:
The feed rollers' bearings and spring function.
Trapezoidal threaded rods, chain and gears for height
adjustment of the table. (Also check chain tension)
The slide for the movable cutter.
The chain transmission for the feed rollers.
Cutter knives, spacers, pressure rollers and side rollers.
If the movable cutter is in the same position for an
extended period (e.g., due to longer series of the
same panel) it can rust. Set the cutter to its maxi-
mum position and minimum position at some point
each month and lubricate the crank's threaded rod
and the slot's rods.
If the machine is not used for a longer period
of time:
Disconnect the power.
Carefully clean the entire machine and perform the
same maintenance as after each work session. Do not
forget the lubrication points.
Remove cutter knives, cutter wedges and pressure
rollers. Store these well-lubricated and at room tem-
perature.
Other:
The out-feed roller, i.e. the rubber roller, wears and
must be replaced when its function is affected by wear.
Signs of wear may be increased presence of out-feed
marks or boards not being fed out from the machine.
