- Tshawb xyuas cov saw hlau tsis tu ncua rau qhov tawg, qhov gouges, hnav, elongation, nicks, thiab haum.
- Qhov kub thiab txias dhau lossis raug rau cov chaw muaj tshuaj lom neeg xws li cov kua qaub lossis cov kua dej lossis cov pa phem tuaj yeem txo qhov kev ua haujlwm ntawm cov saw hlau.
- Sab laj nrog lub chaw tsim khoom ntawm cov saw hlau yog tias cov saw hlau yuav ua haujlwm sab nraum qhov kub thiab txias uas pom zoo (-40 °F txog 400 °F).
- Tshem cov saw hlau tawm ntawm kev pabcuam yog tias qhov tuab ntawm ib qho ntawm qhov txuas tsawg dua tus nqi tsawg kawg nkaus teev tseg.
- Thaum sib xyaw cov saw hlau lossis cov khoom sib xyaw, txhua yam yuav tsum tau ntsuas ntawm qhov txwv kev ua haujlwm ntawm cov khoom lossis cov saw hlau qis tshaj plaws.
- Xauj peb cov kev xaiv ntawm qib 70 txoj saw hlau thauj khoom, nrog rau cov saw hlau.
