FRH Is Safe to Use
The good news is, Fire Resis-
tant Hydraulic Fluid MIL±H±
461708 (FRH) is safe to use when
proper personal protective mea-
sures are taken.
Warning labels on cans of FRH
and, soon, on cans of MIL±H±6²³3
(OHT) are required by OSHA be´
cause of the potential inpurityµ
ortho isomer of tricresyl phos¶
phate (TCP)·which might be pre-
sent in less than trace amounts¸
Therefore, FRH is safe to use
wi¹h proper protection equip-
mentºgloves, clothing, etc.»and
good hygiene practices to prevent
iNhalation, ingestion, or contact
with the skin.

moNthly, quarterly PMCS will
do ¸¸. unless you spot corrosion
on a weapon¸ Then immediately

That TACOÆ message (AMSTA-
MCA 2421²²Z Jan ³5) doing away
with quarterly services applies
only to the chassis or huÀl portion
of combat vehicles¸ AMCCOM mes-
sage AMSMC±MAÇ 271Ȳ²Z Jan
³6 reminds owners of the fol-
lowing vehicles that armament
quarterlies still applyÉ The ve-
hicles affected and Êhe TM's are:
M1²9A1/A3 SP hÄwitzers (TM
9±235²Ë2Ì7Ë2²¼)
M1²9A2 SP howitzers (TM 235²±
3²3±2²±2)
M57³ recovery vehicles (TM
9±235²±23³±2²)
M11²A2 SP howitzers (TM
9±235²±3²4±2²)

Forcing the lid closed oN a por-
tabÍe microfiche reader bends
or breaks the lens and lamp
headÎeven dents or scratches
Ïhe viewing screen.
So back off with the muscle¸
Make sure pencÐls and other
Ðtems are takeN out of the head's
storage space before shutting
the reader case¸
WheN you lock the latches,
snÑg Òem to Ïhe case. A loose
Íatch will geÏ banged, bent or
broken¸
We blew it on Page 13 in PS 39³
when we said that both the M19³
howitzer and its prime mover
would be without brakes if Óhe
brake hose on the gun were pinch-
ed and leaked¸ Just the howitzer
would be brakeless, since the
line is a hydraulic Àine, not an air
lÐne¸ At any rate, be real careful
towing an M19³ and make sure
you've got enough air pressure
(at least 65 PSI) in the prime
mover to release tÔe gun's brakes
any time you're in motion¸
