Some!Safety!Cautions!
•To$avoid$accidents$and$unnecessary$strain,$make$sure$you’re$using$correct$
working$techniques$and$safety$equipment$when$using$your$Holey-Moley$
Digger.$$If$the$digger$is$too$long$to$use$comfortably,$shorter$extension$tubes$
are$available.$$Do!not!stand!on!ladders!or!unstable!surfaces!when!using!
the!digger.$
$
$
•Call!811!before!you!dig.$It’s$easy,$it’s$free$and$it’s$the$law.$$Allow$a$couple$
days.$You$don’t$want$to$be$digging$into$gas$lines$or$electrical$cables.$$$
$
$
$
$
•Wear!protective!gloves.$$The$digger$blades$are$sharp.$$Gloves$will$also$
protect$against$static$electricity$shock.$
$
$
•Wear!gloves.!!Turn!of!the!vacuum!to!let!static!charge!to!dissipate.!!
When$vacuuming$up$dry$materials,$a!static!charge!can!build!up!on!the!
digging!equipment,!hose!and!the!vacuum.$This$is$common$in$a$dry$
climate$when$digging$in$dry$ground.$This$is$similar$to$what$is$experienced$
when$walking$across$dry$carpets.$A$static$electric$shock$is$not$dangerous$to$
persons$but$it$can$cause$a$surprise.$$$Wear$Gloves.$Turn$your$vacuum$off$
and$the$static$electricity$will$rapidly$dissipate.$

•Turn!the!vacuum!off!before!removing!the!hose.!!!
•Dirt,$sand,$and$stones$travel$through$the$vacuum$tubing$at$high$velocities.$$
•Do$not$remove$the$hose$while$the$shop$vacuum$is$operating$–$dirt$can$be$
moving$at$over$100mph$up$the$vacuum$tube$and$it$will$continue$to$flow$for$
a$second$after$pulling$the$hose$off.$$This$can$be$dangerous$to$the$face$and$
eyes.$$$
$
$
•Wear!a!protective!mask!when!working!around!dust,$especially$when$

•The$Bi-Metal$saw$blade$is$extremely$hard$and$rarely$needs$any$attention.$$
Remember$that$it$will$cut$through$metal,$so$if$you$dig$next$to$a$steel$water$

Using!the!Digger!

To$use$the$digger,$attach$a$2-1/2$inch$vacuum$hose$to$the$top$of$the$digger$vacuum$
pipe.$$The$2-1/2$inch$hose$that$comes$with$larger$shop$vacuums$will$have$a$loose$fit$
and$will$easily$rotate.$$The$following$photos$show$the$hose$and$digger$open$ends$

The$following$photo$shows$the$vacuum$hose$attached$over$the$open$end$of$the$

swing$back$and$forth.$$This$will$help$keep$the$hose$from$swinging$while$you$are$
rotating$the$digger.$$A$sealed$vacuum$connection$is$not$required.$$Some$air$coming$
through$at$this$point$in$the$suction$line$actually$helps$transport$dirt$through$the$
vacuum$hose$and$will$keep$the$hose$connection$clear$of$dirt.$$

As$you$penetrate$the$ground,$the$progress$will$be$slow$for$the$first$few$inches$until$

sand,$and$gravel$are$traveling$through$the$hose.$$The$momentum$of$the$particles$will$
continue$to$move$at$high$velocities;$over$100$mph$and$can$cause$eye$damage.$$It$is$
strongly$suggested$that$you$wear$safety$glasses.$$$Even$so,$if$you$have$to$remove$the$
hose,$keep$your$face$away$from$the$digger$vacuum$tube$outlet.$$The$most$dangerous$
situation$is$when$two$people$are$at$the$digger$and$one$person$removes$the$hose$

pulverizing$the$soil$to$make$smaller$particles$for$easy$transport.$$As$the$small$rocks$
move$up$toward$the$vacuum$line,$they$will$be$sucked$into$the$line$to$the$shop$
vacuum.$$Rocks$that$are$too$large$will$stay$in$the$hole.$$These$loose$rocks$can$easily$
be$removed$with$the$shop$vacuum$hose$after$the$digger$is$removed.$$Turn$off$the$
vacuum,$remove$the$hose$from$the$top$of$the$digger$and$put$it$into$the$hole$and$turn$
the$vacuum$back$on.$$$Use$the$same$procedure$to$clean$out$your$hole$once$you$are$
finished.$$$

Obstructions!
$
Invariably$you$will$run$into$obstructions.$$If$a$rock$gets$between$the$sidewall$of$the$
hole$and$the$digger$head,$it$can$bind$the$digger.$$Just$lift$the$digger$up$6$inches$or$so$
and$let$the$rock$fall$into$the$hole.$$$
$
Your$are$being$reminded$here$again:$$Make$sure$you$know$where$you$are$digging$
and$if$there$are$any$wires,$cables,$or$pipes$under$the$digger.$$The$digger$blade$will$
cut$through$metal$pipe$and$will$sever$electrical$conduit$and$underground$cables.$$To$
protect$yourself,$$wear$gloves.$$Dig$as$if$you$know$you$will$be$digging$into$a$conduit$
or$cable.$$Learn$the$feel$of$the$digger$and$you$will$be$able$to$sense$obstructions$
easily.$$Pull$the$digger$out$of$the$ground,$clean$the$hole$and$visually$look$at$the$
obstructions.$
$
Impediments!

The$digger$works$on$the$principle$of$Wind$Erosion.$$Water,$as$one$might$expect$will$
be$the$biggest$impediment$to$this$principle.$$The$digger$works$best$in$dry$soils$up$to$
about$50%$moisture.$$Wet$clay$will$tend$to$clog$up$the$digger$head.$$It$will$dry$on$the$
blades.$This$can$be$unclogged$easily$with$a$screwdriver,$as$most$of$the$clogging$will$
occur$right$at$the$entrance$to$the$digger$head.$$Washing$the$digger$head$with$water$
can$also$be$done.$$Soil$that$is$too$wet$will$not$work$well.$$$
$
The$digger,$well$suited$for$most$materials,$it$was$not$made$for$ROCK.$$$The$best$way$
to$deal$with$rocks$is$to$use$other$implements$to$make$the$hole$bigger$to$remove$the$
rock$or$to$move$your$hole.$$If$the$soil$is$too$wet,$our$Core$Digger$that$is$made$to$pull$
out$plugs$of$soil,$may$be$more$suitable.$$In$some$cases,$just$using$the$vacuum$hose$
will$work.$$
