T450WS 1-1
Section 1: Introduction
The T450WS is a compact, maneuverable truck or track mounted drill rig with a
large volume, high-pressure air compressor. A deck mounted diesel engine
provides reliable power for all hydraulic and air systems. The rig top head
drive rotation and efficient pipe handling mean high productivity on the job site.
The T450WS is configured for drilling water wells, monitoring wells, blast-holes,
geothermal bores, and mineral exploration with down-the-hole hammer and
mud rotary techniques.

Service and Support
For service and support, telephone the Customer Service department at
00+1+610-696-2500. Have the serial number available when contacting
service. See Rig Identification for information on the serial number. For a
complete list of parts, service, and sales personnel visit www.schramminc.com.
Rig Identification
Please locate the serial number of the rig and place the number in the space
provided below. Please provide the model number and serial number of the rig
into Table 1-2. The model number is located on both sides of the vehicle. The
serial number is located on a plate to the left-rear side of the rig. If any contact
needs to be made to Schramm®
, Inc. service personnel, the model and serial
number will be required for your convenience. This will ensure that Schramm,
Inc. service personnel will be able to quickly find the data necessary for your
particular rig. Table 1-2 is provided for your convenience when the engine
manufacturer or Schramm needs to be contacted. Refer to Section 11 for
troubleshooting information to determine the problem on the rig. First
determine if the problem is an engine problem. If the problem is not an engine
problem, contact Schramm. Contacting Schramm service personnel about
engine problems will only result in Schramm, Inc. informing you to call the
Engine manufacturer. Schramm is not responsible for service calls relating to
OEM equipment (deck engine, compressor, or carrier).

Definition of Terms
Throughout the manual and on the T450WS drill rig are various Danger,
Caution, Warning, Notice, and Attention signs. Each sign has a unique
significance. It is in the best interest of everyone involved with the rig to not
only read and get familiar with these indications, but to obey them. The terms
are defined as follows:

T450WS1-4
• DANGER: Danger is used to indicate a hazard that will cause severe
personal injury, death, or property damage. Abide by the danger indication.
Do not ignore the danger indication.
• WARNING: Warning is used to indicate a hazard that can cause severe
personal injury, death, or property damage. Heed the warning. Do not
ignore the warning indication.
• CAUTION: Caution is used to indicate a hazard that can cause some
personal injury or property damage. Though it is not as severe as a
warning or danger, the Caution indication is still important due to the injury
or damage caused. It further provides information that is useful to the
operator to avoid a more serious problem. An example of this is the sticker
on the control panel face that mentions the jib boom capacity when
extended versus retracted.
• NOTICE: Notice is used to inform operators and service personnel of
important maintenance information.
• ATTENTION: The large yellow Attention labels are used to indicate
information to help prevent damage to the rig.

Introduction
This manual has been created to educate and stress safe operation and
maintenance of the T450WS rig. Drilling is inherently dangerous, and can
cause property damage, severe injury, or death. Following the guidelines and
instructions in this manual, along with using common sense while around the
rig, will greatly reduce the possibility of a serious/fatal accident occurring.
Please read the Operation and Maintenance manual and all safety instructions
supplied with this equipment before any operation or servicing occurs. Study
the manual and know how to use the drill in a safe and efficient manner.
Follow all safety start-up procedures before operating the rig. Safety is of the
utmost importance when operating the rig. If you do not understand any
instruction, contact Schramm, Inc.
IMPROPER USE, INCORRECT MAINTENANCE,
OR UNAUTHORIZED ALTERATION OF THIS
EQUIPMENT CAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR
DEATH.
Track mounted equipment is powered by the rig’s hydraulic system.
Modifications to these hydraulic circuits could affect unintended
speed, brake, or rotational movements, which can result in property
damage, severe injury, or death.
Do not make any alterations to the equipment without the proper written
consent of the manufacturer. Any equipment alteration without written consent
of the manufacturer voids the warranty and can cause property damage,
severe injury, or death.
The Drilling Safety Guide should be read and used as a reference. The Drilling
Safety Guide, published by the National Drilling Association (formerly the
International Drilling Federation), is an acknowledged handbook of safety
procedures for drilling equipment users. Copies can be obtained from the

Who is Responsible for Safety?
Everyone is responsible for their own safety, and they should always be aware
of their surroundings since drilling is inherently dangerous. Further, the
machine operator (and safety supervisor) must take responsibility for safe
operation and maintenance of the machine. The operator must understand the
operational features of the machine, use care and common sense during its
operation, and ensure that co-workers and observers follow all the safety
procedures. The Drilling Safety Guide, instructions and guidelines in this
manual, and the Point of Hazard labels on the rig provide reminders and
principles for working safely.
Protective Attire
Wear protective attire when working around the drill rig. Always wear a hard
hat, protective shoes, and protective glasses
around the rig. Wear electrically insulated gloves
and boots when working around any form of
electric current to prevent shock or death.
Respirators should be used when working in a
volatile atmosphere to prevent internal damage to
the body such as Silicosis (a disabling,
nonreversible, and sometimes fatal lung disease
cause by overexposure to breathable crystalline
silica).
Do not wear loose clothes or allow untied hair around the rig. Instead, wear
tight clothing and confine the hair when around the rig to avoid the rig from
pulling at the body.
Noise levels will vary with the applied drilling method, the operational
parameters of the drill rig, and the sound reflecting characteristics of the drill
site. Hearing protection must be used.
Hearing protection must be used by everyone working or visiting at or near the drilling site.
Failure to use hearing protection could result in partial or complete hearing loss.
Noise Levels and Hearing Protection
Understand the choice of sound reduction capabilities that can be used at your site.
Ensure exposure does not exceed the maximum capability of the hearing protection.
Ensure that signs indicating that hearing protection must be worn is visible for anyone to
see at the drill site. Follow all laws and meet the ordinances of your locality.
