Do NOT use sealant when joining flare fittings.
Do NOT use Teflon TM (PTFE based) sealant
(tape or paste) on pipe thread fittings. These
sealants can be blown out of high pressure
joints and may damage the hydraulic compo-
nents. See Figure 8-78.
High pressure hydraulic sealant such as Loc-
tite TM product 545 is the only suitable product
for sealing pipe thread fittings on this tiller.
Proper fluid for this tiller attachment is a pre-
mium grade, anti-wear petroleum based
hydraulic fluid which meets ISO AW-32/SAE
10W viscosity rating or MTD part number 737-
3121 (one-gallon container).
Always use two wrenches to separate flare fit-
tings; one to hold the fixed side stationary and
one to rotate the part to be removed. See Fig-
ure 8-79.
