feed Rate
The.speed.at.which.the.saw.blade.will.cut.through.
a.workpiece.is.controlled.by.blade.type.and.feed.
rate.
The.feed.rate.is.controlled.by.the.valve.lever.and.
feed. rate. dial. on. the. hydraulic. cylinder. shown. in.
figure 22.
To set the feed rate:
1.. Raise.the.headstock.and.turn.the.valve.lever.
sideways.(horizontally).
2.. Clamp.the.workpiece.in.the.table.vise.
3.. Move.the.headstock.and.blade.a.few.inches.
above.the.workpiece..
4.. With. the. correct. saw. blade. installed. and.
blade.speed.selected,.turn.the.saw. ON.
5.. Slowly.rotate.the.feed.rate.dial.to.a.conserva-
tive.feed.rate.until.the.saw.begins.to.cut.the.
workpiece.
6.. Observe. the. chips. that. exit. the. cut,. and.
increase.or.decrease.the.feed.rate.according.
to.the.chip.characteristics.(see.
figure 23).
Chips.are.silvery,.
thin,.small,.or.

Valve.Lever
Feed.Rate.Dial
Turning.the.valve.lever.in-line.with.the.piping.(as.
shown.in.the.
figure 22).opens.it.up,.which.allows.
the.fluid.to.circulate.and.allows.the.head.to.move..
Turning.the.valve.lever.sideways.or.perpendicular.
to.the.pipiing.closes.it,.which.locks.the.headstock.
in.place.
The.feed.rate.dial.controls.the.amount.of.fluid.that.
circulates.around.the.hydraulic.cylinder,.which.in.
turn,.controls.the.speed.that.it.moves.
