17 This machine is deigned for planing wood products only Do not use to plane any kind of substance
other then wood
18 Never start the planer while a workpiece is in contact with the cutterhead or knives
19 Always feed workpiece against the rotation of the cutterhead
20 Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm Some examples
of these chemicals are:
•Lead from lead-based paint
•Crystalline silica from bricks and cement and other masonry products
•Arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often you do this type of work To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as those dust masks that are specifically designed to filter out microscopic particles

Maintenance
WARNING!
Disc nnect the machine fr m p wer s urce
bef re pr ceeding with any maintenance,
lubricati n r assembly! Failure t c mply
may cause seri us injury!
•Periodic, or regular inspections are required
to ensure that the machine is in proper
adjustment, and that all hardware is tight
•Clean out-feed rollers and table with a non-
flammable solvent to remove pitch, gum and
other unwanted build-up
•Periodically clean the inside of the machine
for dust control
•Keep pulleys and belts free from dirt, dust,
oil and grease Replace worn v-belts as
needed
•Replace worn knives or sharpen If a knife
gets nicked stagger the knives Move one
knife no more than 1/8” to the right and
another knife no more than 1/8” to the left
•There are three limit switches on the planer,
one that triggers if the hood is open, and a
raising and a lowering limit switch to prevent
the table from automatically traveling too far
Keep these clean and blown out with an air
hose
17

Lubricati n
•Add a few drops of medium weight oil to the
six oil cups (A, Figure 25) weekly or every
eight hours of use (which ever comes first)
•Lubricate the two table elevation screws (B,
Figure 26) as needed Raise the table and
remove the two screws holding the top of
the accordion cover (C, Figure 26) in place
Pull the cover down and lightly grease the
elevating screws, see Figure 26
•Use an oiled cloth to wipe the ways (D,
Figure 26) weekly
•Lubricate the chain system with an oiled
cloth as needed
•The gear box oil should be changed once a
year Remove the drain plug (E, Figure 27)
to drain the oil Refill the gear box with 60-
90 weight gear oil through the fill hole (F,
Figure 27) until the sight glass reads full
The sight glass (G, Figure 27) should be
checked periodically and oil added as
necessary
18

19

Halted Feeding
If the in-feed roll takes stock away from you while feeding, then feeding stops before contacting the
knives, the chipbreaker is probably too low Or the in-feed roller is not set low enough, or does not have
