comply with all of these warnings may cause
serious injury.
3. Replace the warning labels if they become
obscured or removed.
4. This box and pan brake is designed and
intended for use by properly trained and
experienced personnel only. If you are not
familiar with the proper and safe operation of a
brake, do not use until proper training and
knowledge have been obtained.
5. Do not use this brake for other than its intended
use. If used for other purposes, JET disclaims
any real or implied warranty and holds itself
harmless from any injury that may result from
that use.
6. Always wear ANSI Z87.1 approved safety
glasses or face shield while using this drum
sander. (Everydayeyeglasses only have impact
resistant lenses; they are not safety glasses.)
7. Before operating this machine, remove tie,
rings, watches and other jewelry, and roll
sleeves up past the elbows. Do not wear loose
clothing. Confine long hair. Non-slip footwear or
anti-skid floor strips are recommended.
8. Wear ear protectors (plugs or muffs) if noise
reaches unsafe levels.
9. Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contain 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, cement and
other masonry products.
•Arsenic and chromium from chemically
treated lumber.
Your risk of exposure 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 face or dust masks that are
specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under
the influence of drugs, alcohol or any
medication.
11. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and adjusting
wrenches are removed from the machine
before turning it on.
12. Keep safety guards in place at all times when
the machine is in use. If removed for
maintenance purposes, use extreme caution
and replace the guards immediately after
completion of maintenance.
13. Check damaged parts. Before further use of the
machine, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving parts, breakage of parts,
mounting and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or
replaced.

area and non-glare, overhead lighting.
15. Keep the floor around the machine clean and
free of scrap material, oil and grease.

area. Keep children away.
17. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
18. Give your work undivided attention. Looking
around, carrying on a conversation and “horse-
play” are careless acts that can result in serious
injury.

you do not fall into the blade or other moving
parts. Do not overreach or use excessive force
to perform any machine operation.

5.3 Unpacking and cleanup
1. Remove all contents from shipping crate and
compare to the contents list in this manual. If
shipping damage or any part shortages are
identified, contact your distributor. Do not
discard packing material until brake is
assembled and operating satisfactorily.
2. Carefully clean all rust protected surfaces with
a mild solvent or kerosene and a soft rag. Do
not use lacquer thinner, paint thinner, or
gasoline – these will damage painted surfaces.
3. Coat all machined surfaces with a light coat of
oil to inhibit rust.
5.4 Assembly
Refer to exploded view if additional clarification is
needed for assembly.
1. Remove bolts holding support legs and brake to
pallet.
2. Locate brake in a dry, well-lighted area with a
sturdy, level floor. Machine location must allow
room for loading and offloading stock, and
access on all sides for maintenance.
3. Use hoist or forklift to carefully lift brake onto
support legs. Secure with M12 bolts, washers
and nuts (HP1/HP4/HP6/HP8).
Do not allow anyone
beneath brake while moving it into position
and until it is secured on support legs.
4. Verify that brake is level; use shims if
necessary. Secure support legs to floor with
appropriate fasteners, such as lag bolts (not
provided).
5. Install counterweight assemblies to left and
right hinges with M12 bolts, lock washers and
flat washers (HP1/HP4/HP6). See Figure 3.
