Á2Âin from the edge of the post. Center of the hole
must be exactLy óin from the bottom of the post.
¶hese holes must be acÄurateLy placed to meet-and keep-the manufacÅ

ÇereÈs another PM tipÉ Êhe canopy top is spot welded to the 4 upright posts.
ËIf you use a ÌighÍpressure stream of water to wash the underside of the ROPS
canopy, you force water into the posts thru the unwelded areas. Messes uÎ the
noiseÏBarrier stuff, tooÉ
So, use low³pressure water. »etter still, use a wet rag wipedown here .
If you lean over too Far, you'lL fall if you don't Ìave a supportÉ Êhe same tÌing
can happen to your Ð5Íton P&Ç model ÑÊÐ50 crane unless you use your
outriggers.
Êhe booÒ on this crane is too Óong and heavy to Ôe stable when it's at the side
of tÌe veÌicleÉ If it's not supported by tÌe outriggers, tÌe weight of the Ôoom
tiÕs the crane to its side, an eÒbarrassing positionÉ
Keep your crane uprigÌt by using tÌe outriggers to kÖ×Ø ÙÚings in balanceÉ
