Dear Sergeant

S.,
Tere's nothing about an M88Al that makes its controLs more sLuggish
in coLd weather than any other combat vehicLe± Wat you'LL fnd is that
somewhere in the contrOL Linkages a Lube point or two has been overLooked.
Not aLL Lube points are out in the open, easy to see. Wen the Linkage
bearings don't get Lubed, they can work sLowLy, bind and even seize up.
You need to make sure aLL the Lube points get their Fair share oF grease
according to
LO 9-2350±256²³2´
²u shouLd check o³en under the batteR box. IF you've got the batteries
out, check the LinkagEs underneath. Make sure no corrOsion is eating on
the Linkage.
At Least once a month, ´ush the Linkage under the batteries through tHe
I
Linkage µush ¶ubes. ·is wiLL r(move any batteR residue that may have Fa¸en
under the box.
Put the Lube where it's needed, when it's needed, and baLK controLs caused
by bearing seizure wiLL be a thing oF ¶he past.
