▼ HEY! TORQUE BOY: READ BEFORE YOU INSTALL DECKED ▼
1. DON'T over tighten bolts, get em' good 'ole hand-tight.
2. DON'T use power tools.
3. If you don't follow directions and do use power tools:
1). Set clutch at a very low setting.
2). Don't blow it.
3). If you blow it, see NOTE.*
NOTE* Two extra threaded inserts are included in BAG
PREP-EXTRA. That's all you get.
4). DON'T over tighten J-hooks during installation. Make
'em good and snug enough to keep the system from
moving in the bed.
5). Start all bolts with fingers to avoid cross-threading.
NOTE: In your BAG PREP-MT6 or MT8, you will have two
types of 1" length bolts and flanged nuts. One bolt has
a 1/4" diameter, and the other bolt has a 5/16" diameter.
Don't screw this up! The flanged nuts only fit one type
of bolt, so you better at least get that right...
