MECHANICAL MAINTENANCE
CLEANING THE BASE AND TOP SHELL
To clean the gauge base, use a putty knife to scrape away any built-
up accumulations of soil or asphalt.
Be careful not to damage the
gauge base! After removing any large accumulations, wipe the
gauge base with a cloth soaked in WD-40
→
(see note below). The
WD-40 should remove the remaining debris.
The 3450 gauge top shell is manufactured from an engineering
thermoplastic designed specifically to provide high impact strength
and to offer excellent compatibility with many industrial solvents
and petro-chemicals. The top shell may be cleaned with mild (low
alkaline) soap and water. Other approved cleaning substances
include: methyl, isopropyl, or isobutyl alcohols. A cloth dampened
with kerosene or diesel fuel may be used to remove heavy soils.
Avoid prolonged exposure and do not soak.
CAUTION
– EUROPEAN COUNTRIES –
Do not separate the control unit from the base.
Doing so will result in non-compliance with EMC
directive. Call your Troxler representative for
additional information.
CAUTION
WD-40 can damage the keypad. Do not allow WD-40 to
come in contact with the keypad! The keypad may be
cleaned using a mild soap (such as 409 or Fantastic ),
followed by clean water.
CAUTION
The use of any unapproved cleaning agents such as
methyl-ethyl-ketones, amines, and methylene
chloride will damage the top shell and void the
warranty.
