You can start the chaplet with this prayer:
O Jesus, Divine Redeemer, be merciful to us and to the whole world.
R./ Amen.
God powerful, God holy, God immortal, have mercy on us and on the whole world.
R./ Amen.
Grace, mercy, my Jesus during the present dangers; cover us with thy Precious Blood.
R./ Amen.
Eternal Father, grant us mercy through the Blood of Jesus Christ, thy only Son; grant us mercy, we beseech thee.
R./ Amen.
On small beads: My Jesus, pardon and mercy.
R./ Through the merits of thy Holy Wounds.
(Ind. of 300 days, each day)
On large beads: Eternal Father, I offer thee the Wounds of Our Lord Jesus Christ.
R./ To heals those of our souls.
(Ind. of 300 days, each day, H.H. Pius XI. Sacred Penitentiary, Jan. 16, 1924).
The Chaplet is ended, saying thrice:
"Eternal Father, I offer thee the Wounds of Our Lord Jesus Christ.
R./ To heals those of our souls.
My little children, you have to deposit all your concerns, all your sufferings into the Sacred Wounds of my Divine Son.
Offer the bloody and triumphant Wounds of Jesus to the Eternal Father through my Sorrowful and Immaculate Heart and graces shall descend upon you in profusion.
The Eternal Father cannot refuse anything at the sight of the Holy Wounds of his beloved Son...
I come to this blessed place to relieve suffering and convert sinners.
Keep trusting, pray a great deal. Love, help the poor, the sick, the elderly. I bless you with all my Heart...
Apparition of Our Lady on April 14, 1997 in the Blessed Forest; Le Frechou, France. Extract from the Book: "God's Messenger Told Me" (Messages from Our Lady and Our Lord to Bishop Jean Marie).
A humble Lay Sister, Sr. Marie Marthe Chambon, who died in the Chambery Visitation convent (March 21, 1907), assured that she had learned these two invocations from Our Lord Himself.
She declared having received from Him a twofold mission: the one, to (personally) invoke unceasingly the Holy Wounds, and the other, to revive this devotion into the world.
Our Lord would find pleasure in training Sr. Marie Marthe to her mission, by giving her almost daily a kind of "Catechism of the Holy Wounds", catechism on which she had to report to her Superior; following are some echoes of them:
Devotion to the Holy Wounds is grounded upon the most solid foundations: the infinite merits of the Savior
"My daughter, do you recognize the treasure of the world?"
"When you offer my Divine Wounds to my Father, you earn an immense fortune."
"You should not remain poor... Your wealth?... It is my holy Passion. This treasure belongs to you."
"My Father takes pleasure in the offering of my Holy Wounds... offering them to Him is offering Him his own glory, it is offering Heaven to Heaven!"
"My Holy Wounds support the world."
This devotion presents itself as surrounded by the most encouraging promises.
"I shall grant all what will be requested to me through the invocation to my Holy Wounds. You need to spread this devotion."
"You shall obtain all things, because it is the merit of my Blood which is of an infinite price."
"With my Wounds and my Divine Heart, you can obtain all things."
"From my Wounds come out fruits of holiness."
"My Wounds shall repair yours."
This devotion contains precious advantages for the detail of daily life.
"When you experience some sorrow, or have something to suffer, you need to bring it hastily into my Wounds, and your sorrow shall be softened."
"Offer me your actions... united to my Holy Wounds, there are incomprehensible riches, even into the least ones."
You need to have recourse to it in favor of the Sick.
"You have to often repeat before the sick this invocation:
"My Jesus, pardon and mercy, through the merits of thy Holy Wounds!
"This prayer shall soothe both the soul and body."
In Favor of the Dying.
"It is necessary to expire while kissing these sacred Wounds".
"There shall be no death for the soul who will expire in my Wounds: they give true life."
"The way of my Wounds is so simple, so easy to reach Heaven!..."
In Favor of Sinners.
"My Wounds shall cover all your faults."
"Offer them to me often for sinners, for: I thirst for souls."
"The sinner who will say the following prayer: "Eternal Father, I offer thee the Wounds of Our Lord Jesus Christ to heal those of our souls", shall obtain is own conversion".
"With every word of the Chaplet of Mercy you pronounce, I let a drop of my blood drip on the soul of a sinner."
"This Chaplet of Mercy balances my Justice, it stops my vengeance."
In favor of the Souls in Purgatory.
"The benefit of the Holy Wounds makes graces come down from Heaven, and Holy Souls come up onto Heaven."
"The Holy Wounds are the treasure of treasures for the Souls in Purgatory."
In Favor of the Church.
"My daughter, you need to properly fulfill you task, which is to offer my divine Wounds to me in Favor of Sinners. "My Wounds shall cover all your faults." "Offer them to me often for sinners, for: I thirst for souls."
"The sinner who will say the following prayer: "Eternal Father, I offer thee the Wounds of Our Lord Jesus Christ to heal those of our souls", shall obtain his conversion". "With every word of the Chaplet of Mercy you pronounce, I let a drop of my blood drip on the soul of a sinner."
"This Chaplet of Mercy balances my Justice, it stops my vengeance."
"I would like to see all my Spouses be "Crucifixes."
"My daughter, look at my crown, and you shall see mortification, -my hands stretched out, and you shall learn obedience, -you shall understand poverty when you see me all unclothed on the Cross, -Purity in the One who is so pure and who loves you as your Spouse! "Everywhere, you will find Wounds in your Spouse." "This is where those I have chosen and who want to attain glory must walk." "I want you to be a standing victim!"
