Limited Warranty and Limitation Liability
BW Technologies LP (BW) warrants the product to be free from defects in material and workmanship under normal use and service for a period of two years, beginning on the date of
shipment to the buyer. This warranty extends only to the sale of new and unused products to the original buyer. BW’s warranty obligation is limited, at BW’s option, to refund of the purchase
price, repair or replacement of a defective product that is returned to a BW authorized service center within the warranty period. In no event shall BW’s liability hereunder exceed the
purchase price actually paid by the buyer for the Product.
This warranty does not include:
a) fuses, disposable batteries or the routine replacement of parts due to the normal wear and tear of the product arising from use;
b) any product which in BW’s opinion, has been misused, altered, neglected or damaged, by accident or abnormal conditions of operation, handling or use;
c) any damage or defects attributable to repair of the product by any person other than an authorized dealer, or the installation of unapproved parts on the product; or
The obligations set forth in this warranty are conditional on:
a) proper storage, installation, calibration, use, maintenance and compliance with the product manual instructions and any other applicable recommendations of BW;
b) the buyer promptly notifying BW of any defect and, if required, promptly making the product available for correction. No goods shall be returned to BW until receipt by the buyer of
shipping instructions from BW; and
c) the right of BW to require that the buyer provide proof of purchase such as the original invoice, bill of sale or packing slip to establish that the product is within the warranty period.
THE BUYER AGREES THAT THIS WARRANTY IS THE BUYER’S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY
IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PAR TIC ULA R PURPOSE. BW SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT, INCIDENTAL, OR BASED ON CONTRACT, TORT OR RELIANCE
OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or limitation of incidental or consequential damages, the limitations and exclusions of
this warranty may not apply to every buyer. If any provision of this warranty is held invalid or unenforceable by a court of competent jurisdiction, such holding will not affect the validity or

Introduction
a Warning
To ensure personal safety, read Safety Information -
Read First and aCautions before using the detector.
The GasAlertMaxXT II gas detector (“the detector”) warns of hazardous
gas at levels above user-defined alarm setpoints.
The detector is a personal safety device. It is your responsibility to
respond properly to the alarm.

Safety Information - Read First
Use the detector only as specified in this technical reference guide,
otherwise the protection provided by the detector may be impaired.
International symbols used on the detector and in this technical
reference guide are defined in
Read the aCautions on the following pages before using the detector.
ec Warning
This instrument contains a lithium polymer battery.
Dispose of lithium cells immediately. Do not
disassemble and do not dispose of in fire. Do not mix
with the solid waste stream. Spent batteries must be
disposed of by a qualified recycler or hazardous
materials handler.

GasAlertMaxXT II
Safety Information - Read First
aCautions
• Warning: Substitution of components may impair Intrinsic Safety.
• Caution: For safety reasons, this equipment must be operated and serviced by qualified personnel only. Read and
understand the technical reference guide completely before operating or servicing.
• Do not use the detector if it is damaged. Inspect the detector before using. Look for cracks and/or missing parts.
• If the detector is damaged or parts are missing, contact BW Technologies by Honeywell
• Use only sensor(s) that are specifically designed for the GasAlertMaxXT II model. Refer to Replacement Parts and
Accessories.
• Calibrate the detector before first-time use and then on a regular schedule, depending on use and sensor exposure to
poisons and contaminants. Sensors must be calibrated regularly and at least once every 180 days (6 months).
• BW recommends to bump test the sensors, before each day’s use, to confirm their ability to respond to gas by
exposing the detector to a gas concentration that exceeds the alarm setpoints. Manually verify that the audible and
visual alarms are activated. Calibrate if the readings are not within the specified limits.
• Protect the combustible sensor from exposure to lead compounds, silicones, and chlorinated hydrocarbons.
Although certain organic vapors (such as leaded gasoline and halogenated hydrocarbons) may temporarily inhibit
sensor performance, in most cases, the sensor will recover after calibration.
• BW recommends the combustible sensor be checked with a known concentration of calibration gas after any known
exposure to catalyst contaminants/poisons (sulfur compounds, silicon vapors, halogenated compounds, etc).
• The combustible sensor is factory calibrated to 50% LEL methane. If monitoring a different combustible gas in the
% LEL range, calibrate the sensor using the appropriate gas.
• Warning: High off-scale LEL readings may indicate an explosive concentration.
• Only the combustible gas detection portion of this instrument has been assessed for performance by CSA
International.
• For use only in potentially explosive atmospheres where oxygen concentrations do not exceed 20.9% (v/v).
• Any rapid up-scaling reading followed by a declining or erratic reading may indicate a gas concentration beyond
upper scale limit, which may be hazardous.
• Calibrate only in a safe area that is free of hazardous gas.
immediately.

GasAlertMaxXT II
User Manual
• Use only BW approved batteries for the GasAlertMaxXT II detector. Refer to Replacement Parts and Accessories.
• Charge the detector before first-time use. BW recommends the detector be charged after every workday.
• Charge the GasAlertMaxXT II using the recommended charging adapter only. Do not use any other charging adapter.
Failure to adhere to this precaution can lead to fire and/or explosion. Read and adhere to all instructions in the
charger operator’s manual. Failure to do so can result in fire, electrical shock, personal injury, and/or property
damage.
• Extended exposure of the GasAlertMaxXT II to certain concentrations of combustible gases and air may stress a
detector element, which can seriously affect its performance. If an alarm occurs due to high concentration of
combustible gases, recalibration should be performed, or if needed, the sensor replaced.
• Do not test the combustible sensor’s response with a butane cigarette lighter; doing so will damage the sensor.
• Do not expose the detector to electrical shock or severe continuous mechanical shock.
• Do not immerse the detector in liquids.
• The pump (XT-RPUMP-K1) is certified for use with the GasAlertMaxXT II detector only.
• Do not attempt to disassemble, adjust, or service the detector unless instructions for that procedure are provided in
the technical reference guide and/or that part is listed as a replacement part. Use only BW Technologies by Honeywell
Replacement Parts and Accessories
• The detector warranty will be voided if customer, personnel, or third parties damage the detector during repair
attempts. Non-BW Technologies by Honeywell repair/service attempts void this warranty.
aCautions
.
• Warning: The lithium battery (MX-BAT01) may present a risk of fire or chemical burn hazard if misused. Do not
disassemble, heat above 212°F (100°C), or incinerate.
• Do not use any other lithium batteries with the GasAlertMaxXT II detector. Use of any other cell can cause fire and/or
explosion. To order and replace the MX-BAT01 battery, refer to Replacement Parts and Accessories.

GasAlertMaxXT II
Safety Information - Read First
aCautions
• Warning: Lithium polymer cells exposed to heat at 266°F (130°C) for 10 minutes can cause fire and/or explosion.
• Dispose of used lithium cells immediately. Do not disassemble and do not dispose of in fire. Do not mix with the solid
waste stream. Spent batteries must be disposed of by a qualified recycler or hazardous materials handler.
• Keep lithium cells away from children.
• Calibration cylinders that are used with a demand flow regulator must meet the following maximum inlet pressure
specifications:
• Disposable cylinders 0-3000 psig/70 bar
• Refillable cylinders 0-3000 psig/70 bar
