Preface
This manual provides the information you need to successfully perform major maintenance on your
TriScrollTM Dry Vacuum Pump. The time to perform major rebuild is typically 18,000 hours of run time.
If you have questions that are not addressed in this manual, please contact the nearest Agilent service
facility listed on the rear cover of this manual.
Safety Considerations
READ THE FOLLOWING INSTRUCTIONS. TAKE ALL NECESSARY PRECAUTIONS.
The following format is used in this manual to call attention to hazards:
Maintenance personnel must be aware of all hazards associated with this equipment. They must
know how to recognize hazardous and potentially hazardous conditions, and know how to avoid
them. The consequences of work performed by unskilled or improperly trained maintenance personnel,
or careless operation of the equipment employed in the specified maintenance procedures can be
serious.
Every maintenance person must read and thoroughly understand the materials discussed and the
instructions provided in this manual, as well as any additional information provided by Agilent.
WARNING The warning messages are for attracting
the attention of the operator to a partic-
ular procedure or practice which, if not
followed correctly, could lead to serious
injury.
CAUTION The caution messages are displayed
before procedures, which if not fol-
lowed, could cause damage to the
equipment.
NOTE The notes contain important informa-
tion taken from the text.

All warnings and cautions must be read carefully, fully understood, and strictly observed. Consult local,
state/province, and national agencies regarding specific requirements and regulations. Address any
safety, operation, and/or maintenance questions to the nearest Agilent location.
WARNING Disconnect power from the TriScroll
300 before performing any mainte-
nance procedure.
Allow the pump to cool before perform-
ing any maintenance procedure.
Approximate cool-down time is one to
two hours.
CAUTION Wipe all O-rings clean with a lint-free
cloth before installation to ensure that
no foreign matter is present to impair
the seal.
Do not use alcohol, methanol or other
solvents on O-rings. To do so causes
deterioration and reduces their ability to
hold a vacuum.
If applicable, apply a small amount of
Krytox
®
GPL 224 grease and wipe the
O-rings “shiny” dry.
NOTE Agilent recommends replacing all
O-rings during routine maintenance or
during any maintenance procedure
requiring that O-rings be removed.
Unless otherwise stated, apply
Loctite
®
242 or Loctite PST
®
to the first
few threads only. Apply just enough to
obtain a seal.
WARNING The TriScroll 300 weighs 26.4 kg
(58 lbs). To avoid injury, use proper lift-
ing techniques when moving the pump.

Major Maintenance
General Information
Agilent TriScroll 300 series pumps are designed to provide years of trouble-free service if maintenance
procedures and intervals are observed. Bearing grease replenishment and tip seal replacement are
recommended when the pump base pressure has risen to an unacceptably high level for your
application. Bearings, rotary seals and O-rings should also be replaced if the pump exhibits humming
or grinding noises from the bearings. Main bearing life may be shortened if your application requires
the pumping of high quantities of water vapor. Use of the bearing purge will keep this water from
impacting bearing life.
Required Equipment
❑Maintenance Tool Kit: PTSS0300TK
❑Major Maintenance Kit: PTSS0300MK
❑Arbor Press: 1/2 ton or larger, 10" work diameter capacity, 8" capacity over table
❑Oven: 400 oF temperature capability, 11" wide x 11" deep x 4" high minimum chamber,
500 watt or higher heating capacity
❑Heat Resistant Surface
❑Vacuum Gauge: Capable of measuring pressure of 5 mTorr to 20 mTorr with an accuracy of
± 1 mTorr. A capacitance manometer or Pirani gauge is recommended.
