12 Part No. 29-MAN-00, Rev. A E.H. Wachs
Hearing Protection
The Hearing Protection hazard label is affixed
to the machine. The highest continuous noise
levels recorded for this equipment exceed 80
dB(A). Equipment operators/maintainers must
wear hearing protection.
SAFE OPERATION OF THE DW GUILLOTINE
Intended Uses
The DW Guillotine is designed to cut pipes of various mate-
rials using an abrasive diamond wire. The machine mounts
to the workpiece being cut off; the workpiece must be
secure and stable to hold the machine, or be adequately sup-
ported. Do not mount the DW Guillotine on non-cylindrical
workpieces.
Proper Use of the DW Guillotine
• This equipment is to be operated, serviced, and main-
tained only by qualified, trained personnel.
Exceeding the maximum
hydraulic pressure or flow
rate can result in equipment
damage or operator harm.
• Hydraulic pressure to the DW Guillotine must not
exceed 2250 psi (155 bar). It is the operator’s responsi-
bility to install and set a pressure limiting relief valve on
the hydraulic power unit. Normal operating pressure is
2000 psi (137 bar).
• Hydraulic flow to the DW Guillotine must not exceed 9
gpm (34 l/min). Normal operating flow is 7-9 gpm (26-
34 l/min).
• Use the DW Guillotine only on horizontal pipe. The
clamping system is not designed to hold it on a vertical
pipe.
• Make sure the equipment is stable when attached to the
workpiece for the operation. The mounting strap must
be tightened securely—as tight as you can get it. Ensur-
ing stability of the installed tool is the responsibility of
the operator.
• Make sure the workpiece is supported adequately for
installation of the equipment. This includes supporting
any workpiece “fall-off” section when severing the
WARNING

Chapter 2, Safety: Safe Operation of the DW Guillotine
E.H. Wachs Part No. 29-MAN-00, Rev. A 13
workpiece. Ensuring support of the workpiece is the
responsibility of the operator.
• It is recommended that you mount the saw so that the
controls are at an appropriate height and convenient to
operate. The recommended height of the controls is 2-5
ft (0.6-1.5 m).
• Use water or coolant on the cutting wire when operating
the DW Guillotine. Water/coolant is required to cool
and lubricate the wire during cutting, and to reduce air-
borne cutting debris. Excessive high temperatures will
cause premature damage to machine components, and
potential burn hazards.
• Tooling on any cutting equipment—including lathe
tools, saw blades, abrasive wire, etc.—may get very hot.
Do not touch tooling until you have made sure it is cool
enough to handle.
• DO NOT wear gloves when operating the DW Guillo-
tine. Gloves can become entangled in rotating machin-
ery, causing serious injury. (You can wear gloves when
removing or cleaning up chips and cutting debris. Chips
can be very sharp and cause cuts.)
• Before performing any service on the equipment, dis-
connect the power source. Follow all lock-out/tag-out
procedures required at the worksite.
Hydraulic Powered Equipment
• Be sure all hoses are connected for correct flow to and
from the DW Guillotine.
• Hydraulic components such as hoses, motors, and mani-
folds will get hot during operation and may cause burns.
Do not touch hydraulic components, except for operator
controls, during or after operating the machine.
Injection of
hydraulic fluid
through the skin
is a serious
injury that can
result in infection, tissue
damage, and possible loss of
limb. Seek medical treat-
ment immediately. First aid
is not sufficient treatment for
injection injury.
•Hydraulic injection injury—A pinhole in a hydraulic hose
or fitting can eject fluid with enough force to pierce
skin. Check hoses and fittings regularly for leaks; see
the instructions in Chapter 4. Do not use bare hands to
check for leaks while the system is pressurized. If you
suspect a leak, move a piece of paper or cardboard at
least 6 inches (15 cm) over the suspicious area and
watch for fluid spraying on the surface.

zontal).
• Disconnect power from the equipment and lock out the
power supply immediately to prevent accidental restart-
ing of the machine.
• Follow all lock-out/tag-out procedures required at the
worksite when disconnecting or servicing the equip-
ment.

direction. The DW Guillotine should never be oper-
ated in reverse direction.
• Do not perform any set-up, maintenance, adjustments,
service, or disassembly of the machinery without first
disconnecting the hydraulic hoses and performing the
required lock-out tag-out (LOTO) procedure to isolate
power from the DW Guillotine.
• Always put the ON/OFF handle in the OFF position
when the machine is not operating, to prevent accidental
starting of the machine (for instance, by turning on the
HPU while connected to the DW Guillotine).
Potential Hazards
Cutting Parts. The DW Guillotine can cut human flesh if
contact is made while the wire is rotating. Keep clear of all
moving parts when operating the machine.

E.H. Wachs Part No. 29-MAN-00, Rev. A 15
Hot Surfaces. Hydraulic components and the cutting wire
become hot during operation. Do not touch any surface
before making sure it is not hot enough to cause burns.
Noise Hazard. The highest continuous noise levels
recorded for this equipment exceed 80 dB(A). Equipment
operators/maintainers must wear hearing protection.
Flying Debris. The DW Guillotine creates airborne dust
and debris during cutting.Always wear impact-resistant eye
protection while operating or working near this equipment.
Use water on the diamond wire during cutting to reduce
heat and suppress airborne debris.
High-Pressure Hydraulic Fluid.A pinhole in a hydraulic
hose or fitting can eject fluid with enough force to pierce
skin. Check hoses and fittings regularly for leaks. Do not
use bare hands to check for leaks while the system is
pressurized.
Outdoor Use. The DW Guillotine is designed for outdoor
use. Do not operate the machine outdoors during or immedi-
ately after (30 minutes) an electrical storm
Lifting Hazard. The DW Guillotine weighs 65 lb (30 kg).
Use of a lifting device is recommended when moving the
machine or mounting it on the workpiece. The DW Guillo-
tine can be lifted by two operators. Make sure that there is
stable footing and adequate clearance to handle the machine
comfortably.
Ignition/Explosion Hazard. The DW Guillotine can pro-
duce heat and sparks during cutting. It is designed to cut
pipes that carry water as a medium; it is not intended for use
with pipes that carry any type of hydrocarbon (petroleum-
based product) or other ATEX-classified materials. To
reduce the risk of fire or explosion, do not use this wire saw
for cutting pipe containing these materials. The user
assumes all risks if this wire saw is misused in this type of
application.

Residual Risks
• Hot surfaces on hydraulic components after operation.
• Hot surfaces on the cutting wire and the workpiece after
cutting.
• Cut hazards of abrasive cutting wire.
• Noise hazard during operation of the machine.
• Entanglement hazards from moving parts of the
machine.
• Handling of potentially hazardous materials, including
fluids and lubricants used for operation and mainte-
nance of the machine.
• Trip hazards from hydraulic hoses.
• Slip and fall hazards from spilled hydraulic fluid or
lubricants.
Disconnecting Power
Power is disconnected by removing the hydraulic hoses
from the fittings on the DW Guillotine. The wire drive
mechanism will not operate or move when power is discon-
nected.
Disconnecting the hydraulic hoses from the fittings on
the machine is the only way to completely isolate power
from the DW Guillotine.Always disconnect the hoses
when the machine is not in an operating situation.
Figure 2-1. To disconnect power, remove the hydrau-
lic hoses from their fittings.
